Handling compressed file formats like ZIP/GZIP or PNG -cannot be implemented without having this functionality. -Applications that handle these formats are either using their own, -duplicated code, or not using the ZLib unit at all. - -Here are a few suggestions: - -- Checksum class wrappers around adler32() and crc32(), similar - to the Java classes that implement the java.util.zip.Checksum - interface. - -- The ability to read and write raw deflate streams, without the - zlib stream header and trailer.

Using NAnt: - Open a command prompt with access to the build environment and run nant - in the same directory as the DotZLib.build file. - You can define 2 properties on the nant command-line to control the build: - debug={true|false} to toggle between release/debug builds (default=true). - nunit={true|false} to include or esclude unit tests (default=true). - Also the target clean will remove binaries. - Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release - or ./DotZLib/bin/debug, depending on whether you are building the release - or debug version of the library. - - Examples: - nant -D:debug=false -D:nunit=false - will build a release mode version of the library without unit tests. - nant - will build a debug version of the library with unit tests - nant clean - will remove all previously built files. - - ---------------------------------- -Copyright (c) Henrik Ravn 2004 - -Use, modification and distribution are subject to the Boost Software License, Version 1.0. -(See accompanying file LICENSE_1_0.txt or copy at http://www.boost.org/LICENSE_1_0.txt) diff --git a/cpukit/zlib/contrib/infback9/README b/cpukit/zlib/contrib/infback9/README deleted file mode 100644 index e75ed13294..0000000000 --- a/cpukit/zlib/contrib/infback9/README +++ /dev/null @@ -1 +0,0 @@ -See infback9.h for what this is and how to use it. diff --git a/cpukit/zlib/contrib/infback9/infback9.c b/cpukit/zlib/contrib/infback9/infback9.c deleted file mode 100644 index f5ddde67da..0000000000 --- a/cpukit/zlib/contrib/infback9/infback9.c +++ /dev/null @@ -1,608 +0,0 @@ -/* infback9.c -- inflate deflate64 data using a call-back interface - * Copyright (C) 1995-2003 Mark Adler - * For conditions of distribution and use, see copyright notice in zlib.h - */ - -#include "zutil.h" -#include "infback9.h" -#include "inftree9.h" -#include "inflate9.h" - -#define WSIZE 65536UL - -/* - strm provides memory allocation functions in zalloc and zfree, or - Z_NULL to use the library memory allocation functions. - - window is a user-supplied window and output buffer that is 64K bytes. - */ -int ZEXPORT inflateBack9Init_(strm, window, version, stream_size) -z_stream FAR *strm; -unsigned char FAR *window; -const char *version; -int stream_size; -{ - struct inflate_state FAR *state; - - if (version == Z_NULL || version[0] != ZLIB_VERSION[0] || - stream_size != (int)(sizeof(z_stream))) - return Z_VERSION_ERROR; - if (strm == Z_NULL || window == Z_NULL) - return Z_STREAM_ERROR; - strm->msg = Z_NULL; /* in case we return an error */ - if (strm->zalloc == (alloc_func)0) { - strm->zalloc = zcalloc; - strm->opaque = (voidpf)0; - } - if (strm->zfree == (free_func)0) strm->zfree = zcfree; - state = (struct inflate_state FAR *)ZALLOC(strm, 1, - sizeof(struct inflate_state)); - if (state == Z_NULL) return Z_MEM_ERROR; - Tracev((stderr, "inflate: allocated\n")); - strm->state = (voidpf)state; - state->window = window; - return Z_OK; -} - -/* - Build and output length and distance decoding tables for fixed code - decoding. - */ -#ifdef MAKEFIXED -#include - -void makefixed9(void) -{ - unsigned sym, bits, low, size; - code *next, *lenfix, *distfix; - struct inflate_state state; - code fixed[544]; - - /* literal/length table */ - sym = 0; - while (sym < 144) state.lens[sym++] = 8; - while (sym < 256) state.lens[sym++] = 9; - while (sym < 280) state.lens[sym++] = 7; - while (sym < 288) state.lens[sym++] = 8; - next = fixed; - lenfix = next; - bits = 9; - inflate_table9(LENS, state.lens, 288, &(next), &(bits), state.work); - - /* distance table */ - sym = 0; - while (sym < 32) state.lens[sym++] = 5; - distfix = next; - bits = 5; - inflate_table9(DISTS, state.lens, 32, &(next), &(bits), state.work); - - /* write tables */ - puts(" /* inffix9.h -- table for decoding deflate64 fixed codes"); - puts(" * Generated automatically by makefixed9()."); - puts(" */"); - puts(""); - puts(" /* WARNING: this file should *not* be used by applications."); - puts(" It is part of the implementation of this library and is"); - puts(" subject to change.

* inffast.S is a hand tuned assembler version of: - * - * inffast.c -- fast decoding - * Copyright (C) 1995-2003 Mark Adler - * For conditions of distribution and use, see copyright notice in zlib.h - * - * Copyright (C) 2003 Chris Anderson - * Please use the copyright conditions above. - * - * This version (Jan-23-2003) of inflate_fast was coded and tested under - * GNU/Linux on a pentium 3, using the gcc-3.2 compiler distribution. On that - * machine, I found that gzip style archives decompressed about 20% faster than - * the gcc-3.2 -O3 -fomit-frame-pointer compiled version. Your results will - * depend on how large of a buffer is used for z_stream.next_in & next_out - * (8K-32K worked best for my 256K cpu cache) and how much overhead there is in - * stream processing I/O and crc32/addler32. In my case, this routine used - * 70% of the cpu time and crc32 used 20%. - * - * I am confident that this version will work in the general case, but I have - * not tested a wide variety of datasets or a wide variety of platforms. - * - * Jan-24-2003 -- Added -DUSE_MMX define for slightly faster inflating. - * It should be a runtime flag instead of compile time flag... - * - * Jan-26-2003 -- Added runtime check for MMX support with cpuid instruction. - * With -DUSE_MMX, only MMX code is compiled. With -DNO_MMX, only non-MMX code - * is compiled. Without either option, runtime detection is enabled. Runtime - * detection should work on all modern cpus and the recomended algorithm (flip - * ID bit on eflags and then use the cpuid instruction) is used in many - * multimedia applications. Tested under win2k with gcc-2.95 and gas-2.12 - * distributed with cygwin3. Compiling with gcc-2.95 -c inffast.S -o - * inffast.obj generates a COFF object which can then be linked with MSVC++ - * compiled code. Tested under FreeBSD 4.7 with gcc-2.95. - * - * Jan-28-2003 -- Tested Athlon XP... MMX mode is slower than no MMX (and - * slower than compiler generated code). Adjusted cpuid check to use the MMX - * code only for Pentiums < P4 until I have more data on the P4. Speed - * improvment is only about 15% on the Athlon when compared with code generated - * with MSVC++. Not sure yet, but I think the P4 will also be slower using the - * MMX mode because many of it's x86 ALU instructions execute in .5 cycles and - * have less latency than MMX ops. Added code to buffer the last 11 bytes of - * the input stream since the MMX code grabs bits in chunks of 32, which - * differs from the inffast.c algorithm. I don't think there would have been - * read overruns where a page boundary was crossed (a segfault), but there - * could have been overruns when next_in ends on unaligned memory (unintialized - * memory read). - * - * Mar-13-2003 -- P4 MMX is slightly slower than P4 NO_MMX. I created a C - * version of the non-MMX code so that it doesn't depend on zstrm and zstate - * structure offsets which are hard coded in this file. This was last tested - * with zlib-1.2.0 which is currently in beta testing, newer versions of this - * and inffas86.c can be found at http://www.eetbeetee.com/zlib/ and - * http://www.charm.net/~christop/zlib/ - */ - - -/* - * if you have underscore linking problems (_inflate_fast undefined), try - * using -DGAS_COFF - */ -#if ! defined( GAS_COFF ) && ! defined( GAS_ELF ) - -#if defined( WIN32 ) || defined( __CYGWIN__ ) -#define GAS_COFF /* windows object format */ -#else -#define GAS_ELF -#endif - -#endif /* !

Note that this means -that in order to decompress the deflate data successfully, you need to know -the size of the uncompressed data ahead of time. - -If needed, puff() can determine the size of the uncompressed data with no -output space. This is done by passing dest equal to (unsigned char *)0. Then -the initial value of *destlen is ignored and *destlen is set to the length of -the uncompressed data. So if the size of the uncompressed data is not known, -then two passes of puff() can be used--first to determine the size, and second -to do the actual inflation after allocating the appropriate memory. Not -pretty, but it works. (This is one of the reasons you should be using zlib.) - -The deflate format is self-terminating. If the deflate stream does not end -in *sourcelen bytes, puff() will return an error without reading at or past -endsource. - -On return, *sourcelen is updated to the amount of input data consumed, and -*destlen is updated to the size of the uncompressed data.

A length/distance pair is a coded length followed by a - * coded distance to represent a string that occurs earlier in the - * uncompressed data that occurs again at the current location. - * - * - Literals, lengths, and the end-of-block code are combined into a single - * code of up to 286 symbols. They are 256 literals (0..255), 29 length - * symbols (257..285), and the end-of-block symbol (256). - * - * - There are 256 possible lengths (3..258), and so 29 symbols are not enough - * to represent all of those. Lengths 3..10 and 258 are in fact represented - * by just a length symbol. Lengths 11..257 are represented as a symbol and - * some number of extra bits that are added as an integer to the base length - * of the length symbol. The number of extra bits is determined by the base - * length symbol. These are in the static arrays below, lens[] for the base - * lengths and lext[] for the corresponding number of extra bits. - * - * - The reason that 258 gets its own symbol is that the longest length is used - * often in highly redundant files. Note that 258 can also be coded as the - * base value 227 plus the maximum extra value of 31. While a good deflate - * should never do this, it is not an error, and should be decoded properly. - * - * - If a length is decoded, including its extra bits if any, then it is - * followed a distance code. There are up to 30 distance symbols. Again - * there are many more possible distances (1..32768), so extra bits are added - * to a base value represented by the symbol. The distances 1..4 get their - * own symbol, but the rest require extra bits. The base distances and - * corresponding number of extra bits are below in the static arrays dist[] - * and dext[]. - * - * - Literal bytes are simply written to the output. A length/distance pair is - * an instruction to copy previously uncompressed bytes to the output.

A simple forward copy - * ignoring whether the length is greater than the distance or not implements - * this correctly. You should not use memcpy() since its behavior is not - * defined for overlapped arrays.

Therefore the code descriptions - * are simply a list of code lengths for each symbol. - * - * - The code lengths are stored in order for the symbols, so lengths are - * provided for each of the literal/length symbols, and for each of the - * distance symbols. - * - * - If a symbol is not used in the block, this is represented by a zero as - * as the code length. This does not mean a zero-length code, but rather - * that no code should be created for this symbol. There is no way in the - * deflate format to represent a zero-length code. - * - * - The maximum number of bits in a code is 15, so the possible lengths for - * any code are 1..15. - * - * - The fact that a length of zero is not permitted for a code has an - * interesting consequence. Normally if only one symbol is used for a given - * code, then in fact that code could be represented with zero bits. However - * in deflate, that code has to be at least one bit. So for example, if - * only a single distance base symbol appears in a block, then it will be - * represented by a single code of length one, in particular one 0 bit. This - * is an incomplete code, since if a 1 bit is received, it has no meaning, - * and should result in an error. So incomplete distance codes of one symbol - * should be permitted, and the receipt of invalid codes should be handled. - * - * - It is also possible to have a single literal/length code, but that code - * must be the end-of-block code, since every dynamic block has one. This - * is not the most efficient way to create an empty block (an empty fixed - * block is fewer bits), but it is allowed by the format. So incomplete - * literal/length codes of one symbol should also be permitted. - * - * - If there are only literal codes and no lengths, then there are no distance - * codes. This is represented by one distance code with zero bits. - * - * - The list of up to 286 length/literal lengths and up to 30 distance lengths - * are themselves compressed using Huffman codes and run-length encoding. In - * the list of code lengths, a 0 symbol means no code, a 1..15 symbol means - * that length, and the symbols 16, 17, and 18 are run-length instructions. - * Each of 16, 17, and 18 are follwed by extra bits to define the length of - * the run. 16 copies the last length 3 to 6 times. 17 represents 3 to 10 - * zero lengths, and 18 represents 11 to 138 zero lengths. Unused symbols - * are common, hence the special coding for zero lengths. - * - * - The symbols for 0..18 are Huffman coded, and so that code must be - * described first. This is simply a sequence of up to 19 three-bit values - * representing no code (0) or the code length for that symbol (1..7). - * - * - A dynamic block starts with three fixed-size counts from which is computed - * the number of literal/length code lengths, the number of distance code - * lengths, and the number of code length code lengths (ok, you come up with - * a better name!) in the code descriptions. For the literal/length and - * distance codes, lengths after those provided are considered zero, i.e. no - * code. The code length code lengths are received in a permuted order (see - * the order[] array below) to make a short code length code length list more - * likely. As it turns out, very short and very long codes are less likely - * to be seen in a dynamic code description, hence what may appear initially - * to be a peculiar ordering. - * - * - Given the number of literal/length code lengths (nlen) and distance code - * lengths (ndist), then they are treated as one long list of nlen + ndist - * code lengths. Therefore run-length coding can and often does cross the - * boundary between the two sets of lengths. - * - * - So to summarize, the code description at the start of a dynamic block is - * three counts for the number of code lengths for the literal/length codes, - * the distance codes, and the code length codes. This is followed by the - * code length code lengths, three bits each. This is used to construct the - * code length code which is used to read the remainder of the lengths. Then - * the literal/length code lengths and distance lengths are read as a single - * set of lengths using the code length codes.

- fitblk performs three compression passes on a portion of the input - data in order to determine how much of that input will compress to - nearly the requested output block size. The first pass generates - enough deflate blocks to produce output to fill the requested - output size plus a specfied excess amount (see the EXCESS define - below). The last deflate block may go quite a bit past that, but - is discarded. The second pass decompresses and recompresses just - the compressed data that fit in the requested plus excess sized - buffer. The deflate process is terminated after that amount of - input, which is less than the amount consumed on the first pass. - The last deflate block of the result will be of a comparable size - to the final product, so that the header for that deflate block and - the compression ratio for that block will be about the same as in - the final product. The third compression pass decompresses the - result of the second step, but only the compressed data up to the - requested size minus an amount to allow the compressed stream to - complete (see the MARGIN define below). That will result in a - final compressed stream whose length is less than or equal to the - requested size. Assuming sufficient input and a requested size - greater than a few hundred bytes, the shortfall will typically be - less than ten bytes. - - If the input is short enough that the first compression completes - before filling the requested output size, then that compressed - stream is return with no recompression. - - EXCESS is chosen to be just greater than the shortfall seen in a - two pass approach similar to the above. That shortfall is due to - the last deflate block compressing more efficiently with a smaller - header on the second pass. EXCESS is set to be large enough so - that there is enough uncompressed data for the second pass to fill - out the requested size, and small enough so that the final deflate - block of the second pass will be close in size to the final deflate - block of the third and final pass.

This trailer will be later overwritten. - - Then the last block bit is cleared by seeking back in the file and rewriting - the byte that contains it. Seeking forward, the last byte of the compressed - data is saved along with the number of unused bits to initialize deflate. - - A deflate process is initialized, using the last 32K of the uncompressed - data from the gzip file to initialize the dictionary. If the total - uncompressed data was less than 32K, then all of it is used to initialize - the dictionary. The deflate output bit buffer is also initialized with the - last bits from the original deflate stream. From here on, the data to - append is simply compressed using deflate, and written to the gzip file. - When that is complete, the new CRC-32 and uncompressed length are written - as the trailer of the gzip file. - */ - -#include -#include -#include -#include -#include -#include "zlib.h" - -#define local static -#define LGCHUNK 14 -#define CHUNK (1U << LGCHUNK) -#define DSIZE 32768U - -/* print an error message and terminate with extreme prejudice */ -local void bye(char *msg1, char *msg2) -{ - fprintf(stderr, "gzappend error: %s%s\n", msg1, msg2);

zlib Usage Example

-We often get questions about how the deflate() and inflate() functions should be used. -Users wonder when they should provide more input, when they should use more output, -what to do with a Z_BUF_ERROR, how to make sure the process terminates properly, and -so on. So for those who have read zlib.h (a few times), and -would like further edification, below is an annotated example in C of simple routines to compress and decompress -from an input file to an output file using deflate() and inflate() respectively. The -annotations are interspersed between lines of the code. So please read between the lines. -We hope this helps explain some of the intricacies of zlib. -

-Without further adieu, here is the program zpipe.c: -

-
-We now include the header files for the required definitions. From -stdio.h we use fopen(), fread(), fwrite(), -feof(), ferror(), and fclose() for file i/o, and -fputs() for error messages. From string.h we use -strcmp() for command line argument processing. -From assert.h we use the assert() macro. -From zlib.h -we use the basic compression functions deflateInit(), -deflate(), and deflateEnd(), and the basic decompression -functions inflateInit(), inflate(), and -inflateEnd(). -

-#include <stdio.h>
-#include <string.h>
-#include <assert.h>
-#include "zlib.h"
-
-CHUNK is simply the buffer size for feeding data to and pulling data -from the zlib routines. Larger buffer sizes would be more efficient, -especially for inflate(). If the memory is available, buffers sizes -on the order of 128K or 256K bytes should be used. -

-#define CHUNK 16384
-
-The def() routine compresses data from an input file to an output file. The output data -will be in the zlib format, which is different from the gzip or zip -formats. The zlib format has a very small header of only two bytes to identify it as -a zlib stream and to provide decoding information, and a four-byte trailer with a fast -check value to verify the integrity of the uncompressed data after decoding. -

-/* Compress from file source to file dest until EOF on source.
-   def() returns Z_OK on success, Z_MEM_ERROR if memory could not be
-   allocated for processing, Z_STREAM_ERROR if an invalid compression
-   level is supplied, Z_VERSION_ERROR if the version of zlib.h and the
-   version of the library linked do not match, or Z_ERRNO if there is
-   an error reading or writing the files. */
-int def(FILE *source, FILE *dest, int level)
-{
-
-Here are the local variables for def(). ret will be used for zlib -return codes. flush will keep track of the current flushing state for deflate(), -which is either no flushing, or flush to completion after the end of the input file is reached. -have is the amount of data returned from deflate(). The strm structure -is used to pass information to and from the zlib routines, and to maintain the -deflate() state. in and out are the input and output buffers for -deflate(). -

-    int ret, flush;
-    unsigned have;
-    z_stream strm;
-    char in[CHUNK];
-    char out[CHUNK];
-
-The first thing we do is to initialize the zlib state for compression using -deflateInit(). This must be done before the first use of deflate(). -The zalloc, zfree, and opaque fields in the strm -structure must be initialized before calling deflateInit(). Here they are -set to the zlib constant Z_NULL to request that zlib use -the default memory allocation routines. An application may also choose to provide -custom memory allocation routines here. deflateInit() will allocate on the -order of 256K bytes for the internal state. -(See zlib Technical Details.) -

-deflateInit() is called with a pointer to the structure to be initialized and -the compression level, which is an integer in the range of -1 to 9. Lower compression -levels result in faster execution, but less compression. Higher levels result in -greater compression, but slower execution. The zlib constant Z_DEFAULT_COMPRESSION, -equal to -1, -provides a good compromise between compression and speed and is equivalent to level 6. -Level 0 actually does no compression at all, and in fact expands the data slightly to produce -the zlib format (it is not a byte-for-byte copy of the input). -More advanced applications of zlib -may use deflateInit2() here instead. Such an application may want to reduce how -much memory will be used, at some price in compression. Or it may need to request a -gzip header and trailer instead of a zlib header and trailer, or raw -encoding with no header or trailer at all. -

-We must check the return value of deflateInit() against the zlib constant -Z_OK to make sure that it was able to -allocate memory for the internal state, and that the provided arguments were valid. -deflateInit() will also check that the version of zlib that the zlib.h -file came from matches the version of zlib actually linked with the program. This -is especially important for environments in which zlib is a shared library. -

-Note that an application can initialize multiple, independent zlib streams, which can -operate in parallel. The state information maintained in the structure allows the zlib -routines to be reentrant. -


-    /* allocate deflate state */
-    strm.zalloc = Z_NULL;
-    strm.zfree = Z_NULL;
-    strm.opaque = Z_NULL;
-    ret = deflateInit(&strm, level);
-    if (ret != Z_OK)
-        return ret;
-
-With the pleasantries out of the way, now we can get down to business. The outer do-loop -reads all of the input file and exits at the bottom of the loop once end-of-file is reached. -This loop contains the only call of deflate(). So we must make sure that all of the -input data has been processed and that all of the output data has been generated and consumed -before we fall out of the loop at the bottom. -

-    /* compress until end of file */
-    do {
-
-We start off by reading data from the input file. The number of bytes read is put directly -into avail_in, and a pointer to those bytes is put into next_in. We also -check to see if end-of-file on the input has been reached. If we are at the end of file, then flush is set to the -zlib constant Z_FINISH, which is later passed to deflate() to -indicate that this is the last chunk of input data to compress. We need to use feof() -to check for end-of-file as opposed to seeing if fewer than CHUNK bytes have been read. The -reason is that if the input file length is an exact multiple of CHUNK, we will miss -the fact that we got to the end-of-file, and not know to tell deflate() to finish -up the compressed stream. If we are not yet at the end of the input, then the zlib -constant Z_NO_FLUSH will be passed to deflate to indicate that we are still -in the middle of the uncompressed data. -

-If there is an error in reading from the input file, the process is aborted with -deflateEnd() being called to free the allocated zlib state before returning -the error. We wouldn't want a memory leak, now would we? deflateEnd() can be called -at any time after the state has been initialized. Once that's done, deflateInit() (or -deflateInit2()) would have to be called to start a new compression process. There is -no point here in checking the deflateEnd() return code. The deallocation can't fail. -


-        strm.avail_in = fread(in, 1, CHUNK, source);
-        if (ferror(source)) {
-            (void)deflateEnd(&strm);
-            return Z_ERRNO;
-        }
-        flush = feof(source) ? Z_FINISH : Z_NO_FLUSH;
-        strm.next_in = in;
-
-The inner do-loop passes our chunk of input data to deflate(), and then -keeps calling deflate() until it is done producing output. Once there is no more -new output, deflate() is guaranteed to have consumed all of the input, i.e., -avail_in will be zero. -

-        /* run deflate() on input until output buffer not full, finish
-           compression if all of source has been read in */
-        do {
-
-Output space is provided to deflate() by setting avail_out to the number -of available output bytes and next_out to a pointer to that space. -

-            strm.avail_out = CHUNK;
-            strm.next_out = out;
-
-Now we call the compression engine itself, deflate(). It takes as many of the -avail_in bytes at next_in as it can process, and writes as many as -avail_out bytes to next_out. Those counters and pointers are then -updated past the input data consumed and the output data written. It is the amount of -output space available that may limit how much input is consumed. -Hence the inner loop to make sure that -all of the input is consumed by providing more output space each time. Since avail_in -and next_in are updated by deflate(), we don't have to mess with those -between deflate() calls until it's all used up. -

-The parameters to deflate() are a pointer to the strm structure containing -the input and output information and the internal compression engine state, and a parameter -indicating whether and how to flush data to the output. Normally deflate will consume -several K bytes of input data before producing any output (except for the header), in order -to accumulate statistics on the data for optimum compression. It will then put out a burst of -compressed data, and proceed to consume more input before the next burst. Eventually, -deflate() -must be told to terminate the stream, complete the compression with provided input data, and -write out the trailer check value. deflate() will continue to compress normally as long -as the flush parameter is Z_NO_FLUSH. Once the Z_FINISH parameter is provided, -deflate() will begin to complete the compressed output stream. However depending on how -much output space is provided, deflate() may have to be called several times until it -has provided the complete compressed stream, even after it has consumed all of the input. The flush -parameter must continue to be Z_FINISH for those subsequent calls. -

-There are other values of the flush parameter that are used in more advanced applications. You can -force deflate() to produce a burst of output that encodes all of the input data provided -so far, even if it wouldn't have otherwise, for example to control data latency on a link with -compressed data. You can also ask that deflate() do that as well as erase any history up to -that point so that what follows can be decompressed independently, for example for random access -applications. Both requests will degrade compression by an amount depending on how often such -requests are made. -

-deflate() has a return value that can indicate errors, yet we do not check it here. Why -not? Well, it turns out that deflate() can do no wrong here. Let's go through -deflate()'s return values and dispense with them one by one. The possible values are -Z_OK, Z_STREAM_END, Z_STREAM_ERROR, or Z_BUF_ERROR. Z_OK -is, well, ok. Z_STREAM_END is also ok and will be returned for the last call of -deflate(). This is already guaranteed by calling deflate() with Z_FINISH -until it has no more output. Z_STREAM_ERROR is only possible if the stream is not -initialized properly, but we did initialize it properly. There is no harm in checking for -Z_STREAM_ERROR here, for example to check for the possibility that some -other part of the application inadvertently clobbered the memory containing the zlib state. -Z_BUF_ERROR will be explained further below, but -suffice it to say that this is simply an indication that deflate() could not consume -more input or produce more output. deflate() can be called again with more output space -or more available input, which it will be in this code. -


-            ret = deflate(&strm, flush);    /* no bad return value */
-            assert(ret != Z_STREAM_ERROR);  /* state not clobbered */
-
-Now we compute how much output deflate() provided on the last call, which is the -difference between how much space was provided before the call, and how much output space -is still available after the call. Then that data, if any, is written to the output file. -We can then reuse the output buffer for the next call of deflate(). Again if there -is a file i/o error, we call deflateEnd() before returning to avoid a memory leak. -

-            have = CHUNK - strm.avail_out;
-            if (fwrite(out, 1, have, dest) != have || ferror(dest)) {
-                (void)deflateEnd(&strm);
-                return Z_ERRNO;
-            }
-
-The inner do-loop is repeated until the last deflate() call fails to fill the -provided output buffer. Then we know that deflate() has done as much as it can with -the provided input, and that all of that input has been consumed. We can then fall out of this -loop and reuse the input buffer. -

-The way we tell that deflate() has no more output is by seeing that it did not fill -the output buffer, leaving avail_out greater than zero. However suppose that -deflate() has no more output, but just so happened to exactly fill the output buffer! -avail_out is zero, and we can't tell that deflate() has done all it can. -As far as we know, deflate() -has more output for us. So we call it again. But now deflate() produces no output -at all, and avail_out remains unchanged as CHUNK. That deflate() call -wasn't able to do anything, either consume input or produce output, and so it returns -Z_BUF_ERROR. (See, I told you I'd cover this later.) However this is not a problem at -all. Now we finally have the desired indication that deflate() is really done, -and so we drop out of the inner loop to provide more input to deflate(). -

-With flush set to Z_FINISH, this final set of deflate() calls will -complete the output stream. Once that is done, subsequent calls of deflate() would return -Z_STREAM_ERROR if the flush parameter is not Z_FINISH, and do no more processing -until the state is reinitialized. -

-Some applications of zlib have two loops that call deflate() -instead of the single inner loop we have here. The first loop would call -without flushing and feed all of the data to deflate(). The second loop would call -deflate() with no more -data and the Z_FINISH parameter to complete the process. As you can see from this -example, that can be avoided by simply keeping track of the current flush state. -


-        } while (strm.avail_out == 0);
-        assert(strm.avail_in == 0);     /* all input will be used */
-
-Now we check to see if we have already processed all of the input file. That information was -saved in the flush variable, so we see if that was set to Z_FINISH. If so, -then we're done and we fall out of the outer loop. We're guaranteed to get Z_STREAM_END -from the last deflate() call, since we ran it until the last chunk of input was -consumed and all of the output was generated. -

-        /* done when last data in file processed */
-    } while (flush != Z_FINISH);
-    assert(ret == Z_STREAM_END);        /* stream will be complete */
-
-The process is complete, but we still need to deallocate the state to avoid a memory leak -(or rather more like a memory hemorrhage if you didn't do this). Then -finally we can return with a happy return value. -

-    /* clean up and return */
-    (void)deflateEnd(&strm);
-    return Z_OK;
-}
-
-Now we do the same thing for decompression in the inf() routine. inf() -decompresses what is hopefully a valid zlib stream from the input file and writes the -uncompressed data to the output file. Much of the discussion above for def() -applies to inf() as well, so the discussion here will focus on the differences between -the two. -

-/* Decompress from file source to file dest until stream ends or EOF.
-   inf() returns Z_OK on success, Z_MEM_ERROR if memory could not be
-   allocated for processing, Z_DATA_ERROR if the deflate data is
-   invalid or incomplete, Z_VERSION_ERROR if the version of zlib.h and
-   the version of the library linked do not match, or Z_ERRNO if there
-   is an error reading or writing the files. */
-int inf(FILE *source, FILE *dest)
-{
-
-The local variables have the same functionality as they do for def(). The -only difference is that there is no flush variable, since inflate() -can tell from the zlib stream itself when the stream is complete. -

-    int ret;
-    unsigned have;
-    z_stream strm;
-    char in[CHUNK];
-    char out[CHUNK];
-
-The initialization of the state is the same, except that there is no compression level, -of course, and two more elements of the structure are initialized. avail_in -and next_in must be initialized before calling inflateInit(). This -is because the application has the option to provide the start of the zlib stream in -order for inflateInit() to have access to information about the compression -method to aid in memory allocation. In the current implementation of zlib -(up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of -inflate() anyway. However those fields must be initialized since later versions -of zlib that provide more compression methods may take advantage of this interface. -In any case, no decompression is performed by inflateInit(), so the -avail_out and next_out fields do not need to be initialized before calling. -

-Here avail_in is set to zero and next_in is set to Z_NULL to -indicate that no input data is being provided. -


-    /* allocate inflate state */
-    strm.zalloc = Z_NULL;
-    strm.zfree = Z_NULL;
-    strm.opaque = Z_NULL;
-    strm.avail_in = 0;
-    strm.next_in = Z_NULL;
-    ret = inflateInit(&strm);
-    if (ret != Z_OK)
-        return ret;
-
-The outer do-loop decompresses input until inflate() indicates -that it has reached the end of the compressed data and has produced all of the uncompressed -output. This is in contrast to def() which processes all of the input file. -If end-of-file is reached before the compressed data self-terminates, then the compressed -data is incomplete and an error is returned. -

-    /* decompress until deflate stream ends or end of file */
-    do {
-
-We read input data and set the strm structure accordingly. If we've reached the -end of the input file, then we leave the outer loop and report an error, since the -compressed data is incomplete. Note that we may read more data than is eventually consumed -by inflate(), if the input file continues past the zlib stream. -For applications where zlib streams are embedded in other data, this routine would -need to be modified to return the unused data, or at least indicate how much of the input -data was not used, so the application would know where to pick up after the zlib stream. -

-        strm.avail_in = fread(in, 1, CHUNK, source);
-        if (ferror(source)) {
-            (void)inflateEnd(&strm);
-            return Z_ERRNO;
-        }
-        if (strm.avail_in == 0)
-            break;
-        strm.next_in = in;
-
-The inner do-loop has the same function it did in def(), which is to -keep calling inflate() until has generated all of the output it can with the -provided input. -

-        /* run inflate() on input until output buffer not full */
-        do {
-
-Just like in def(), the same output space is provided for each call of inflate(). -

-            strm.avail_out = CHUNK;
-            strm.next_out = out;
-
-Now we run the decompression engine itself. There is no need to adjust the flush parameter, since -the zlib format is self-terminating. The main difference here is that there are -return values that we need to pay attention to. Z_DATA_ERROR -indicates that inflate() detected an error in the zlib compressed data format, -which means that either the data is not a zlib stream to begin with, or that the data was -corrupted somewhere along the way since it was compressed. The other error to be processed is -Z_MEM_ERROR, which can occur since memory allocation is deferred until inflate() -needs it, unlike deflate(), whose memory is allocated at the start by deflateInit(). -

-Advanced applications may use -deflateSetDictionary() to prime deflate() with a set of likely data to improve the -first 32K or so of compression. This is noted in the zlib header, so inflate() -requests that that dictionary be provided before it can start to decompress. Without the dictionary, -correct decompression is not possible. For this routine, we have no idea what the dictionary is, -so the Z_NEED_DICT indication is converted to a Z_DATA_ERROR. -

-inflate() can also return Z_STREAM_ERROR, which should not be possible here, -but could be checked for as noted above for def(). Z_BUF_ERROR does not need to be -checked for here, for the same reasons noted for def(). Z_STREAM_END will be -checked for later. -


-            ret = inflate(&strm, Z_NO_FLUSH);
-            assert(ret != Z_STREAM_ERROR);  /* state not clobbered */
-            switch (ret) {
-            case Z_NEED_DICT:
-                ret = Z_DATA_ERROR;     /* and fall through */
-            case Z_DATA_ERROR:
-            case Z_MEM_ERROR:
-                (void)inflateEnd(&strm);
-                return ret;
-            }
-
-The output of inflate() is handled identically to that of deflate(). -

-            have = CHUNK - strm.avail_out;
-            if (fwrite(out, 1, have, dest) != have || ferror(dest)) {
-                (void)inflateEnd(&strm);
-                return Z_ERRNO;
-            }
-
-The inner do-loop ends when inflate() has no more output as indicated -by not filling the output buffer, just as for deflate(). -

-        } while (strm.avail_out == 0);
-        assert(strm.avail_in == 0);     /* all input will be used */
-
-The outer do-loop ends when inflate() reports that it has reached the -end of the input zlib stream, has completed the decompression and integrity -check, and has provided all of the output. This is indicated by the inflate() -return value Z_STREAM_END. The inner loop is guaranteed to leave ret -equal to Z_STREAM_END if the last chunk of the input file read contained the end -of the zlib stream. So if the return value is not Z_STREAM_END, the -loop continues to read more input. -

-        /* done when inflate() says it's done */
-    } while (ret != Z_STREAM_END);
-
-At this point, decompression successfully completed, or we broke out of the loop due to no -more data being available from the input file. If the last inflate() return value -is not Z_STREAM_END, then the zlib stream was incomplete and a data error -is returned. Otherwise, we return with a happy return value. Of course, inflateEnd() -is called first to avoid a memory leak. -

-    /* clean up and return */
-    (void)inflateEnd(&strm);
-    return ret == Z_STREAM_END ? Z_OK : Z_DATA_ERROR;
-}
-
-That ends the routines that directly use zlib. The following routines make this -a command-line program by running data through the above routines from stdin to -stdout, and handling any errors reported by def() or inf(). -

-zerr() is used to interpret the possible error codes from def() -and inf(), as detailed in their comments above, and print out an error message. -Note that these are only a subset of the possible return values from deflate() -and inflate(). -


-/* report a zlib or i/o error */
-void zerr(int ret)
-{
-    fputs("zpipe: ", stderr);
-    switch (ret) {
-    case Z_ERRNO:

-}
-
-Here is the main() routine used to test def() and inf(). The -zpipe command is simply a compression pipe from stdin to stdout, if -no arguments are given, or it is a decompression pipe if zpipe -d is used. If any other -arguments are provided, no compression or decompression is performed. Instead a usage -message is displayed. Examples are zpipe < foo.txt > foo.txt.z to compress, and -zpipe -d < foo.txt.z > foo.txt to decompress. -

Introduction

- The 'zlib' compression library provides in-memory compression and - decompression functions, including integrity checks of the uncompressed - data. This version of the library supports only one compression method - (deflation) but other algorithms will be added later and will have the same - stream interface. -

- - Compression can be done in a single step if the buffers are large - enough (for example if an input file is mmap'ed), or can be done by - repeated calls of the compression function. In the latter case, the - application must provide more input and/or consume the output - (providing more output space) before each call. -

- - The library also supports reading and writing files in gzip (.gz) format - with an interface similar to that of stdio. -

- - The library does not install any signal handler. The decoder checks - the consistency of the compressed data, so the library should never - crash even in case of corrupted input. -

- -

-

Utility functions

- The following utility functions are implemented on top of the - basic stream-oriented functions. - To simplify the interface, some - default options are assumed (compression level and memory usage, - standard memory allocation functions). The source code of these - utility functions can easily be modified if you need special options. -

Function description

-
-
int compress (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen); -
- Compresses the source buffer into the destination buffer. sourceLen is - the byte length of the source buffer. Upon entry, destLen is the total - size of the destination buffer, which must be at least 0.1% larger than - sourceLen plus 12 bytes. Upon exit, destLen is the actual size of the - compressed buffer.

- This function can be used to compress a whole file at once if the - input file is mmap'ed.

- compress returns Z_OK if success, Z_MEM_ERROR if there was not - enough memory, Z_BUF_ERROR if there was not enough room in the output - buffer.

- -

int compress2 (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen, int level); -
- Compresses the source buffer into the destination buffer. The level - parameter has the same meaning as in deflateInit. sourceLen is the byte - length of the source buffer. Upon entry, destLen is the total size of the - destination buffer, which must be at least 0.1% larger than sourceLen plus - 12 bytes. Upon exit, destLen is the actual size of the compressed buffer. -

- - compress2 returns Z_OK if success, Z_MEM_ERROR if there was not enough - memory, Z_BUF_ERROR if there was not enough room in the output buffer, - Z_STREAM_ERROR if the level parameter is invalid. -

- -

int uncompress (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen); -
- Decompresses the source buffer into the destination buffer. sourceLen is - the byte length of the source buffer. Upon entry, destLen is the total - size of the destination buffer, which must be large enough to hold the - entire uncompressed data. (The size of the uncompressed data must have - been saved previously by the compressor and transmitted to the decompressor - by some mechanism outside the scope of this compression library.) - Upon exit, destLen is the actual size of the compressed buffer.

- This function can be used to decompress a whole file at once if the - input file is mmap'ed. -

- - uncompress returns Z_OK if success, Z_MEM_ERROR if there was not - enough memory, Z_BUF_ERROR if there was not enough room in the output - buffer, or Z_DATA_ERROR if the input data was corrupted. -

- -

typedef voidp gzFile; -

- -

gzFile gzopen (const char *path, const char *mode); -
- Opens a gzip (.gz) file for reading or writing. The mode parameter - is as in fopen ("rb" or "wb") but can also include a compression level - ("wb9") or a strategy: 'f' for filtered data as in "wb6f", 'h' for - Huffman only compression as in "wb1h". (See the description - of deflateInit2 for more information about the strategy parameter.) -

- - gzopen can be used to read a file which is not in gzip format ; in this - case gzread will directly read from the file without decompression. -

- - gzopen returns NULL if the file could not be opened or if there was - insufficient memory to allocate the (de)compression state ; errno - can be checked to distinguish the two cases (if errno is zero, the - zlib error is Z_MEM_ERROR). -

- -

gzFile gzdopen (int fd, const char *mode); -
- gzdopen() associates a gzFile with the file descriptor fd. File - descriptors are obtained from calls like open, dup, creat, pipe or - fileno (in the file has been previously opened with fopen). - The mode parameter is as in gzopen. -

- The next call of gzclose on the returned gzFile will also close the - file descriptor fd, just like fclose(fdopen(fd), mode) closes the file - descriptor fd. If you want to keep fd open, use gzdopen(dup(fd), mode). -

- gzdopen returns NULL if there was insufficient memory to allocate - the (de)compression state. -

- -

int gzsetparams (gzFile file, int level, int strategy); -
- Dynamically update the compression level or strategy. See the description - of deflateInit2 for the meaning of these parameters. -

- gzsetparams returns Z_OK if success, or Z_STREAM_ERROR if the file was not - opened for writing. -

- -

int gzread (gzFile file, voidp buf, unsigned len); -
- Reads the given number of uncompressed bytes from the compressed file. - If the input file was not in gzip format, gzread copies the given number - of bytes into the buffer. -

- gzread returns the number of uncompressed bytes actually read (0 for - end of file, -1 for error). -

- -

int gzwrite (gzFile file, const voidp buf, unsigned len); -
- Writes the given number of uncompressed bytes into the compressed file. - gzwrite returns the number of uncompressed bytes actually written - (0 in case of error). -

- -

int VA gzprintf (gzFile file, const char *format, ...); -
- Converts, formats, and writes the args to the compressed file under - control of the format string, as in fprintf. gzprintf returns the number of - uncompressed bytes actually written (0 in case of error). -

- -

int gzputs (gzFile file, const char *s); -
- Writes the given null-terminated string to the compressed file, excluding - the terminating null character. -

- gzputs returns the number of characters written, or -1 in case of error. -

- -

char * gzgets (gzFile file, char *buf, int len); -
- Reads bytes from the compressed file until len-1 characters are read, or - a newline character is read and transferred to buf, or an end-of-file - condition is encountered. The string is then terminated with a null - character. -

- gzgets returns buf, or Z_NULL in case of error. -

- -

int gzputc (gzFile file, int c); -
- Writes c, converted to an unsigned char, into the compressed file. - gzputc returns the value that was written, or -1 in case of error. -

- -

int gzgetc (gzFile file); -
- Reads one byte from the compressed file. gzgetc returns this byte - or -1 in case of end of file or error. -

- -

int gzflush (gzFile file, int flush); -
- Flushes all pending output into the compressed file. The parameter - flush is as in the deflate() function. The return value is the zlib - error number (see function gzerror below). gzflush returns Z_OK if - the flush parameter is Z_FINISH and all output could be flushed. -

- gzflush should be called only when strictly necessary because it can - degrade compression. -

- -

z_off_t gzseek (gzFile file, z_off_t offset, int whence); -
- Sets the starting position for the next gzread or gzwrite on the - given compressed file. The offset represents a number of bytes in the - uncompressed data stream. The whence parameter is defined as in lseek(2); - the value SEEK_END is not supported. -

- If the file is opened for reading, this function is emulated but can be - extremely slow. If the file is opened for writing, only forward seeks are - supported ; gzseek then compresses a sequence of zeroes up to the new - starting position. -

- gzseek returns the resulting offset location as measured in bytes from - the beginning of the uncompressed stream, or -1 in case of error, in - particular if the file is opened for writing and the new starting position - would be before the current position. -

- -

int gzrewind (gzFile file); -
- Rewinds the given file. This function is supported only for reading. -

- gzrewind(file) is equivalent to (int)gzseek(file, 0L, SEEK_SET) -

- -

z_off_t gztell (gzFile file); -
- Returns the starting position for the next gzread or gzwrite on the - given compressed file. This position represents a number of bytes in the - uncompressed data stream. -

- - gztell(file) is equivalent to gzseek(file, 0L, SEEK_CUR) -

- -

int gzeof (gzFile file); -
- Returns 1 when EOF has previously been detected reading the given - input stream, otherwise zero. -

- -

int gzclose (gzFile file); -
- Flushes all pending output if necessary, closes the compressed file - and deallocates all the (de)compression state. The return value is the zlib - error number (see function gzerror below). -

- -

const char * gzerror (gzFile file, int *errnum); -
- Returns the error message for the last error which occurred on the - given compressed file. errnum is set to zlib error number. If an - error occurred in the file system and not in the compression library, - errnum is set to Z_ERRNO and the application may consult errno - to get the exact error code. -

Function description

-
-
const char * zlibVersion (void); -
The application can compare zlibVersion and ZLIB_VERSION for consistency. - If the first character differs, the library code actually used is - not compatible with the zlib.h header file used by the application. - This check is automatically made by deflateInit and inflateInit. -

- -

int deflateInit (z_streamp strm, int level); -
- Initializes the internal stream state for compression. The fields - zalloc, zfree and opaque must be initialized before by the caller. - If zalloc and zfree are set to Z_NULL, deflateInit updates them to - use default allocation functions. -

- - The compression level must be Z_DEFAULT_COMPRESSION, or between 0 and 9: - 1 gives best speed, 9 gives best compression, 0 gives no compression at - all (the input data is simply copied a block at a time). -

- - Z_DEFAULT_COMPRESSION requests a default compromise between speed and - compression (currently equivalent to level 6). -

- - deflateInit returns Z_OK if success, Z_MEM_ERROR if there was not - enough memory, Z_STREAM_ERROR if level is not a valid compression level, - Z_VERSION_ERROR if the zlib library version (zlib_version) is incompatible - with the version assumed by the caller (ZLIB_VERSION). - msg is set to null if there is no error message. deflateInit does not - perform any compression: this will be done by deflate(). -

- -

int deflate (z_streamp strm, int flush); -
- deflate compresses as much data as possible, and stops when the input - buffer becomes empty or the output buffer becomes full. It may introduce some - output latency (reading input without producing any output) except when - forced to flush.

- - The detailed semantics are as follows. deflate performs one or both of the - following actions: - -

    -
  • Compress more input starting at next_in and update next_in and avail_in - accordingly. If not all input can be processed (because there is not - enough room in the output buffer), next_in and avail_in are updated and - processing will resume at this point for the next call of deflate(). - -
  • - Provide more output starting at next_out and update next_out and avail_out - accordingly. This action is forced if the parameter flush is non zero. - Forcing flush frequently degrades the compression ratio, so this parameter - should be set only when necessary (in interactive applications). - Some output may be provided even if flush is not set. -

- - Before the call of deflate(), the application should ensure that at least - one of the actions is possible, by providing more input and/or consuming - more output, and updating avail_in or avail_out accordingly ; avail_out - should never be zero before the call. The application can consume the - compressed output when it wants, for example when the output buffer is full - (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK - and with zero avail_out, it must be called again after making room in the - output buffer because there might be more output pending. -

- - If the parameter flush is set to Z_SYNC_FLUSH, all pending output is - flushed to the output buffer and the output is aligned on a byte boundary, so - that the decompressor can get all input data available so far. (In particular - avail_in is zero after the call if enough output space has been provided - before the call.) Flushing may degrade compression for some compression - algorithms and so it should be used only when necessary. -

- - If flush is set to Z_FULL_FLUSH, all output is flushed as with - Z_SYNC_FLUSH, and the compression state is reset so that decompression can - restart from this point if previous compressed data has been damaged or if - random access is desired. Using Z_FULL_FLUSH too often can seriously degrade - the compression. -

- - If deflate returns with avail_out == 0, this function must be called again - with the same value of the flush parameter and more output space (updated - avail_out), until the flush is complete (deflate returns with non-zero - avail_out). -

- - If the parameter flush is set to Z_FINISH, pending input is processed, - pending output is flushed and deflate returns with Z_STREAM_END if there - was enough output space ; if deflate returns with Z_OK, this function must be - called again with Z_FINISH and more output space (updated avail_out) but no - more input data, until it returns with Z_STREAM_END or an error. After - deflate has returned Z_STREAM_END, the only possible operations on the - stream are deflateReset or deflateEnd. -

- - Z_FINISH can be used immediately after deflateInit if all the compression - is to be done in a single step. In this case, avail_out must be at least - 0.1% larger than avail_in plus 12 bytes. If deflate does not return - Z_STREAM_END, then it must be called again as described above. -

- - deflate() sets strm-> adler to the adler32 checksum of all input read - so far (that is, total_in bytes). -

- - deflate() may update data_type if it can make a good guess about - the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered - binary. This field is only for information purposes and does not affect - the compression algorithm in any manner. -

- - deflate() returns Z_OK if some progress has been made (more input - processed or more output produced), Z_STREAM_END if all input has been - consumed and all output has been produced (only when flush is set to - Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example - if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible - (for example avail_in or avail_out was zero). -

- -

int deflateEnd (z_streamp strm); -
- All dynamically allocated data structures for this stream are freed. - This function discards any unprocessed input and does not flush any - pending output. -

- - deflateEnd returns Z_OK if success, Z_STREAM_ERROR if the - stream state was inconsistent, Z_DATA_ERROR if the stream was freed - prematurely (some input or output was discarded). In the error case, - msg may be set but then points to a static string (which must not be - deallocated). -

- -

int inflateInit (z_streamp strm); -
- Initializes the internal stream state for decompression. The fields - next_in, avail_in, zalloc, zfree and opaque must be initialized before by - the caller. If next_in is not Z_NULL and avail_in is large enough (the exact - value depends on the compression method), inflateInit determines the - compression method from the zlib header and allocates all data structures - accordingly ; otherwise the allocation will be deferred to the first call of - inflate. If zalloc and zfree are set to Z_NULL, inflateInit updates them to - use default allocation functions. -

- - inflateInit returns Z_OK if success, Z_MEM_ERROR if there was not enough - memory, Z_VERSION_ERROR if the zlib library version is incompatible with the - version assumed by the caller. msg is set to null if there is no error - message. inflateInit does not perform any decompression apart from reading - the zlib header if present: this will be done by inflate(). (So next_in and - avail_in may be modified, but next_out and avail_out are unchanged.) -

- -

int inflate (z_streamp strm, int flush); -
- inflate decompresses as much data as possible, and stops when the input - buffer becomes empty or the output buffer becomes full. It may some - introduce some output latency (reading input without producing any output) - except when forced to flush. -

- - The detailed semantics are as follows. inflate performs one or both of the - following actions: - -

    -
  • Decompress more input starting at next_in and update next_in and avail_in - accordingly. If not all input can be processed (because there is not - enough room in the output buffer), next_in is updated and processing - will resume at this point for the next call of inflate(). - -
  • Provide more output starting at next_out and update next_out and - avail_out accordingly. inflate() provides as much output as possible, - until there is no more input data or no more space in the output buffer - (see below about the flush parameter). -

- - Before the call of inflate(), the application should ensure that at least - one of the actions is possible, by providing more input and/or consuming - more output, and updating the next_* and avail_* values accordingly. - The application can consume the uncompressed output when it wants, for - example when the output buffer is full (avail_out == 0), or after each - call of inflate(). If inflate returns Z_OK and with zero avail_out, it - must be called again after making room in the output buffer because there - might be more output pending. -

- - If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much - output as possible to the output buffer. The flushing behavior of inflate is - not specified for values of the flush parameter other than Z_SYNC_FLUSH - and Z_FINISH, but the current implementation actually flushes as much output - as possible anyway. -

- - inflate() should normally be called until it returns Z_STREAM_END or an - error. However if all decompression is to be performed in a single step - (a single call of inflate), the parameter flush should be set to - Z_FINISH. In this case all pending input is processed and all pending - output is flushed ; avail_out must be large enough to hold all the - uncompressed data. (The size of the uncompressed data may have been saved - by the compressor for this purpose.) The next operation on this stream must - be inflateEnd to deallocate the decompression state. The use of Z_FINISH - is never required, but can be used to inform inflate that a faster routine - may be used for the single inflate() call. -

- - If a preset dictionary is needed at this point (see inflateSetDictionary - below), inflate sets strm-adler to the adler32 checksum of the - dictionary chosen by the compressor and returns Z_NEED_DICT ; otherwise - it sets strm-> adler to the adler32 checksum of all output produced - so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or - an error code as described below. At the end of the stream, inflate() - checks that its computed adler32 checksum is equal to that saved by the - compressor and returns Z_STREAM_END only if the checksum is correct. -

- - inflate() returns Z_OK if some progress has been made (more input processed - or more output produced), Z_STREAM_END if the end of the compressed data has - been reached and all uncompressed output has been produced, Z_NEED_DICT if a - preset dictionary is needed at this point, Z_DATA_ERROR if the input data was - corrupted (input stream not conforming to the zlib format or incorrect - adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent - (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not - enough memory, Z_BUF_ERROR if no progress is possible or if there was not - enough room in the output buffer when Z_FINISH is used. In the Z_DATA_ERROR - case, the application may then call inflateSync to look for a good - compression block. -

- -

int inflateEnd (z_streamp strm); -
- All dynamically allocated data structures for this stream are freed. - This function discards any unprocessed input and does not flush any - pending output. -

- - inflateEnd returns Z_OK if success, Z_STREAM_ERROR if the stream state - was inconsistent. In the error case, msg may be set but then points to a - static string (which must not be deallocated). -

Advanced functions

Function list

Function description

-
-
int deflateInit2 (z_streamp strm, int level, int method, int windowBits, int memLevel, int strategy); - -
This is another version of deflateInit with more compression options. The - fields next_in, zalloc, zfree and opaque must be initialized before by - the caller.

- - The method parameter is the compression method. It must be Z_DEFLATED in - this version of the library.

- - The windowBits parameter is the base two logarithm of the window size - (the size of the history buffer). It should be in the range 8..15 for this - version of the library. Larger values of this parameter result in better - compression at the expense of memory usage. The default value is 15 if - deflateInit is used instead.

- - The memLevel parameter specifies how much memory should be allocated - for the internal compression state. memLevel=1 uses minimum memory but - is slow and reduces compression ratio ; memLevel=9 uses maximum memory - for optimal speed. The default value is 8. See zconf.h for total memory - usage as a function of windowBits and memLevel.

- - The strategy parameter is used to tune the compression algorithm. Use the - value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a - filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no - string match). Filtered data consists mostly of small values with a - somewhat random distribution. In this case, the compression algorithm is - tuned to compress them better. The effect of Z_FILTERED is to force more - Huffman coding and less string matching ; it is somewhat intermediate - between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects - the compression ratio but not the correctness of the compressed output even - if it is not set appropriately.

- - deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough - memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid - method). msg is set to null if there is no error message. deflateInit2 does - not perform any compression: this will be done by deflate().

- -

int deflateSetDictionary (z_streamp strm, const Bytef *dictionary, uInt dictLength); -
- Initializes the compression dictionary from the given byte sequence - without producing any compressed output. This function must be called - immediately after deflateInit, deflateInit2 or deflateReset, before any - call of deflate. The compressor and decompressor must use exactly the same - dictionary (see inflateSetDictionary).

- - The dictionary should consist of strings (byte sequences) that are likely - to be encountered later in the data to be compressed, with the most commonly - used strings preferably put towards the end of the dictionary. Using a - dictionary is most useful when the data to be compressed is short and can be - predicted with good accuracy ; the data can then be compressed better than - with the default empty dictionary.

- - Depending on the size of the compression data structures selected by - deflateInit or deflateInit2, a part of the dictionary may in effect be - discarded, for example if the dictionary is larger than the window size in - deflate or deflate2. Thus the strings most likely to be useful should be - put at the end of the dictionary, not at the front.

- - Upon return of this function, strm-> adler is set to the Adler32 value - of the dictionary ; the decompressor may later use this value to determine - which dictionary has been used by the compressor. (The Adler32 value - applies to the whole dictionary even if only a subset of the dictionary is - actually used by the compressor.)

- - deflateSetDictionary returns Z_OK if success, or Z_STREAM_ERROR if a - parameter is invalid (such as NULL dictionary) or the stream state is - inconsistent (for example if deflate has already been called for this stream - or if the compression method is bsort). deflateSetDictionary does not - perform any compression: this will be done by deflate().

- -

int deflateCopy (z_streamp dest, z_streamp source); -
- Sets the destination stream as a complete copy of the source stream.

- - This function can be useful when several compression strategies will be - tried, for example when there are several ways of pre-processing the input - data with a filter. The streams that will be discarded should then be freed - by calling deflateEnd. Note that deflateCopy duplicates the internal - compression state which can be quite large, so this strategy is slow and - can consume lots of memory.

- - deflateCopy returns Z_OK if success, Z_MEM_ERROR if there was not - enough memory, Z_STREAM_ERROR if the source stream state was inconsistent - (such as zalloc being NULL). msg is left unchanged in both source and - destination.

- -

int deflateReset (z_streamp strm); -
This function is equivalent to deflateEnd followed by deflateInit, - but does not free and reallocate all the internal compression state. - The stream will keep the same compression level and any other attributes - that may have been set by deflateInit2.

- - deflateReset returns Z_OK if success, or Z_STREAM_ERROR if the source - stream state was inconsistent (such as zalloc or state being NULL).

- -

int deflateParams (z_streamp strm, int level, int strategy); -
- Dynamically update the compression level and compression strategy. The - interpretation of level and strategy is as in deflateInit2. This can be - used to switch between compression and straight copy of the input data, or - to switch to a different kind of input data requiring a different - strategy. If the compression level is changed, the input available so far - is compressed with the old level (and may be flushed); the new level will - take effect only at the next call of deflate().

- - Before the call of deflateParams, the stream state must be set as for - a call of deflate(), since the currently available input may have to - be compressed and flushed. In particular, strm-> avail_out must be - non-zero.

- - deflateParams returns Z_OK if success, Z_STREAM_ERROR if the source - stream state was inconsistent or if a parameter was invalid, Z_BUF_ERROR - if strm->avail_out was zero.

- -

int inflateInit2 (z_streamp strm, int windowBits); - -
This is another version of inflateInit with an extra parameter. The - fields next_in, avail_in, zalloc, zfree and opaque must be initialized - before by the caller.

- - The windowBits parameter is the base two logarithm of the maximum window - size (the size of the history buffer). It should be in the range 8..15 for - this version of the library. The default value is 15 if inflateInit is used - instead. If a compressed stream with a larger window size is given as - input, inflate() will return with the error code Z_DATA_ERROR instead of - trying to allocate a larger window.

- - inflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough - memory, Z_STREAM_ERROR if a parameter is invalid (such as a negative - memLevel). msg is set to null if there is no error message. inflateInit2 - does not perform any decompression apart from reading the zlib header if - present: this will be done by inflate(). (So next_in and avail_in may be - modified, but next_out and avail_out are unchanged.)

- -

int inflateSetDictionary (z_streamp strm, const Bytef *dictionary, uInt dictLength); -
- Initializes the decompression dictionary from the given uncompressed byte - sequence. This function must be called immediately after a call of inflate - if this call returned Z_NEED_DICT. The dictionary chosen by the compressor - can be determined from the Adler32 value returned by this call of - inflate. The compressor and decompressor must use exactly the same - dictionary (see deflateSetDictionary).

- - inflateSetDictionary returns Z_OK if success, Z_STREAM_ERROR if a - parameter is invalid (such as NULL dictionary) or the stream state is - inconsistent, Z_DATA_ERROR if the given dictionary doesn't match the - expected one (incorrect Adler32 value). inflateSetDictionary does not - perform any decompression: this will be done by subsequent calls of - inflate().

- -

int inflateSync (z_streamp strm); - -
Skips invalid compressed data until a full flush point (see above the - description of deflate with Z_FULL_FLUSH) can be found, or until all - available input is skipped. No output is provided.

- - inflateSync returns Z_OK if a full flush point has been found, Z_BUF_ERROR - if no more input was provided, Z_DATA_ERROR if no flush point has been found, - or Z_STREAM_ERROR if the stream structure was inconsistent. In the success - case, the application may save the current current value of total_in which - indicates where valid compressed data was found. In the error case, the - application may repeatedly call inflateSync, providing more input each time, - until success or end of the input data.

- -

int inflateReset (z_streamp strm); -
- This function is equivalent to inflateEnd followed by inflateInit, - but does not free and reallocate all the internal decompression state. - The stream will keep attributes that may have been set by inflateInit2. -

- - inflateReset returns Z_OK if success, or Z_STREAM_ERROR if the source - stream state was inconsistent (such as zalloc or state being NULL). -

Function description

-
-
uLong adler32 (uLong adler, const Bytef *buf, uInt len); -
- Update a running Adler-32 checksum with the bytes buf[0..len-1] and - return the updated checksum. If buf is NULL, this function returns - the required initial value for the checksum. -

- An Adler-32 checksum is almost as reliable as a CRC32 but can be computed - much faster. Usage example: - 

-
-     uLong adler = adler32(0L, Z_NULL, 0);
-
-     while (read_buffer(buffer, length) != EOF) {
-       adler = adler32(adler, buffer, length);
-     }
-     if (adler != original_adler) error();
-
- -
uLong crc32 (uLong crc, const Bytef *buf, uInt len); -
- Update a running crc with the bytes buf[0..len-1] and return the updated - crc. If buf is NULL, this function returns the required initial value - for the crc. Pre- and post-conditioning (one's complement) is performed - within this function so it shouldn't be done by the application. - Usage example: - 
-
-     uLong crc = crc32(0L, Z_NULL, 0);
-
-     while (read_buffer(buffer, length) != EOF) {
-       crc = crc32(crc, buffer, length);
-     }
-     if (crc != original_crc) error();

- - The application must update next_in and avail_in when avail_in has - dropped to zero. It must update next_out and avail_out when avail_out - has dropped to zero. The application must initialize zalloc, zfree and - opaque before calling the init function. All other fields are set by the - compression library and must not be updated by the application.

- - The opaque value provided by the application will be passed as the first - parameter for calls of zalloc and zfree. This can be useful for custom - memory management. The compression library attaches no meaning to the - opaque value.

- - zalloc must return Z_NULL if there is not enough memory for the object. - If zlib is used in a multi-threaded application, zalloc and zfree must be - thread safe.

- - On 16-bit systems, the functions zalloc and zfree must be able to allocate - exactly 65536 bytes, but will not be required to allocate more than this - if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS, - pointers returned by zalloc for objects of exactly 65536 bytes *must* - have their offset normalized to zero. The default allocation function - provided by this library ensures this (see zutil.c). To reduce memory - requirements and avoid any allocation of 64K objects, at the expense of - compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h). -

- - The fields total_in and total_out can be used for statistics or - progress reports. After compression, total_in holds the total size of - the uncompressed data and may be saved for use in the decompressor - (particularly if the decompressor wants to decompress everything in - a single step).

- Frequently Asked Questions about ZLIB1.DLL - - -This document describes the design, the rationale, and the usage -of the official DLL build of zlib, named ZLIB1.DLL. If you have -general questions about zlib, you should see the file "FAQ" found -in the zlib distribution, or at the following location: - http://www.gzip.org/zlib/zlib_faq.html - - - 1. What is ZLIB1.DLL, and how can I get it? - - - ZLIB1.DLL is the official build of zlib as a DLL. - (Please remark the character '1' in the name.) - - Pointers to a precompiled ZLIB1.DLL can be found in the zlib - web site at: - http://www.zlib.org/ - - Applications that link to ZLIB1.DLL can rely on the following - specification: - - * The exported symbols are exclusively defined in the source - files "zlib.h" and "zlib.def", found in an official zlib - source distribution. - * The symbols are exported by name, not by ordinal. - * The exported names are undecorated. - * The calling convention of functions is "C" (CDECL). - * The ZLIB1.DLL binary is linked to MSVCRT.DLL. - - The archive in which ZLIB1.DLL is bundled contains compiled - test programs that must run with a valid build of ZLIB1.DLL. - It is recommended to download the prebuilt DLL from the zlib - web site, instead of building it yourself, to avoid potential - incompatibilities that could be introduced by your compiler - and build settings. If you do build the DLL yourself, please - make sure that it complies with all the above requirements, - and it runs with the precompiled test programs, bundled with - the original ZLIB1.DLL distribution. - - If, for any reason, you need to build an incompatible DLL, - please use a different file name. - - - 2. Why did you change the name of the DLL to ZLIB1.DLL? - What happened to the old ZLIB.DLL? - - - The old ZLIB.DLL, built from zlib-1.1.4 or earlier, required - compilation settings that were incompatible to those used by - a static build. The DLL settings were supposed to be enabled - by defining the macro ZLIB_DLL, before including "zlib.h". - Incorrect handling of this macro was silently accepted at - build time, resulting in two major problems: - - * ZLIB_DLL was missing from the old makefile. When building - the DLL, not all people added it to the build options. In - consequence, incompatible incarnations of ZLIB.DLL started - to circulate around the net. - - * When switching from using the static library to using the - DLL, applications had to define the ZLIB_DLL macro and - to recompile all the sources that contained calls to zlib - functions. Failure to do so resulted in creating binaries - that were unable to run with the official ZLIB.DLL build. - - The only possible solution that we could foresee was to make - a binary-incompatible change in the DLL interface, in order to - remove the dependency on the ZLIB_DLL macro, and to release - the new DLL under a different name. - - We chose the name ZLIB1.DLL, where '1' indicates the major - zlib version number. We hope that we will not have to break - the binary compatibility again, at least not as long as the - zlib-1.x series will last. - - There is still a ZLIB_DLL macro, that can trigger a more - efficient build and use of the DLL, but compatibility no - longer dependents on it. - - - 3. Can I build ZLIB.DLL from the new zlib sources, and replace - an old ZLIB.DLL, that was built from zlib-1.1.4 or earlier? - - - In principle, you can do it by assigning calling convention - keywords to the macros ZEXPORT and ZEXPORTVA. In practice, - it depends on what you mean by "an old ZLIB.DLL", because the - old DLL exists in several mutually-incompatible versions. - You have to find out first what kind of calling convention is - being used in your particular ZLIB.DLL build, and to use the - same one in the new build. If you don't know what this is all - about, you might be better off if you would just leave the old - DLL intact. - - - 4. Can I compile my application using the new zlib interface, and - link it to an old ZLIB.DLL, that was built from zlib-1.1.4 or - earlier? - - - The official answer is "no"; the real answer depends again on - what kind of ZLIB.DLL you have. Even if you are lucky, this - course of action is unreliable. - - If you rebuild your application and you intend to use a newer - version of zlib (post- 1.1.4), it is strongly recommended to - link it to the new ZLIB1.DLL. - - - 5. Why are the zlib symbols exported by name, and not by ordinal? - - - Although exporting symbols by ordinal is a little faster, it - is risky. Any single glitch in the maintenance or use of the - DEF file that contains the ordinals can result in incompatible - builds and frustrating crashes. Simply put, the benefits of - exporting symbols by ordinal do not justify the risks. - - Technically, it should be possible to maintain ordinals in - the DEF file, and still export the symbols by name. Ordinals - exist in every DLL, and even if the dynamic linking performed - at the DLL startup is searching for names, ordinals serve as - hints, for a faster name lookup. However, if the DEF file - contains ordinals, the Microsoft linker automatically builds - an implib that will cause the executables linked to it to use - those ordinals, and not the names. It is interesting to - notice that the GNU linker for Win32 does not suffer from this - problem. - - It is possible to avoid the DEF file if the exported symbols - are accompanied by a "__declspec(dllexport)" attribute in the - source files. You can do this in zlib by predefining the - ZLIB_DLL macro. - - - 6. I see that the ZLIB1.DLL functions use the "C" (CDECL) calling - convention. Why not use the STDCALL convention? - STDCALL is the standard convention in Win32, and I need it in - my Visual Basic project! - - (For readability, we use CDECL to refer to the convention - triggered by the "__cdecl" keyword, STDCALL to refer to - the convention triggered by "__stdcall", and FASTCALL to - refer to the convention triggered by "__fastcall".) - - - Most of the native Windows API functions (without varargs) use - indeed the WINAPI convention (which translates to STDCALL in - Win32), but the standard C functions use CDECL. If a user - application is intrinsically tied to the Windows API (e.g. - it calls native Windows API functions such as CreateFile()), - sometimes it makes sense to decorate its own functions with - WINAPI. But if ANSI C or POSIX portability is a goal (e.g. - it calls standard C functions such as fopen()), it is not a - sound decision to request the inclusion of , or to - use non-ANSI constructs, for the sole purpose to make the user - functions STDCALL-able. - - The functionality offered by zlib is not in the category of - "Windows functionality", but is more like "C functionality". - - Technically, STDCALL is not bad; in fact, it is slightly - faster than CDECL, and it works with variable-argument - functions, just like CDECL. It is unfortunate that, in spite - of using STDCALL in the Windows API, it is not the default - convention used by the C compilers that run under Windows. - The roots of the problem reside deep inside the unsafety of - the K&R-style function prototypes, where the argument types - are not specified; but that is another story for another day. - - The remaining fact is that CDECL is the default convention. - Even if an explicit convention is hard-coded into the function - prototypes inside C headers, problems may appear. The - necessity to expose the convention in users' callbacks is one - of these problems. - - The calling convention issues are also important when using - zlib in other programming languages. Some of them, like Ada - (GNAT) and Fortran (GNU G77), have C bindings implemented - initially on Unix, and relying on the C calling convention. - On the other hand, the pre- .NET versions of Microsoft Visual - Basic require STDCALL, while Borland Delphi prefers, although - it does not require, FASTCALL. - - In fairness to all possible uses of zlib outside the C - programming language, we choose the default "C" convention. - Anyone interested in different bindings or conventions is - encouraged to maintain specialized projects. The "contrib/" - directory from the zlib distribution already holds a couple - of foreign bindings, such as Ada, C++, and Delphi. - - - 7. I need a DLL for my Visual Basic project. What can I do? - - - Define the ZLIB_WINAPI macro before including "zlib.h", when - building both the DLL and the user application (except that - you don't need to define anything when using the DLL in Visual - Basic). The ZLIB_WINAPI macro will switch on the WINAPI - (STDCALL) convention. The name of this DLL must be different - than the official ZLIB1.DLL. - - Gilles Vollant has contributed a build named ZLIBWAPI.DLL, - with the ZLIB_WINAPI macro turned on, and with the minizip - functionality built in. For more information, please read - the notes inside "contrib/vstudio/readme.txt", found in the - zlib distribution. - - - 8. I need to use zlib in my Microsoft .NET project. What can I - do? - - - Henrik Ravn has contributed a .NET wrapper around zlib. Look - into contrib/dotzlib/, inside the zlib distribution. - - - 9. If my application uses ZLIB1.DLL, should I link it to - MSVCRT.DLL? Why? - - - It is not required, but it is recommended to link your - application to MSVCRT.DLL, if it uses ZLIB1.DLL. - - The executables (.EXE, .DLL, etc.) that are involved in the - same process and are using the C run-time library (i.e. they - are calling standard C functions), must link to the same - library. There are several libraries in the Win32 system: - CRTDLL.DLL, MSVCRT.DLL, the static C libraries, etc. - Since ZLIB1.DLL is linked to MSVCRT.DLL, the executables that - depend on it should also be linked to MSVCRT.DLL. - - -10. Why are you saying that ZLIB1.DLL and my application should - be linked to the same C run-time (CRT) library? I linked my - application and my DLLs to different C libraries (e.g. my - application to a static library, and my DLLs to MSVCRT.DLL), - and everything works fine. - - - If a user library invokes only pure Win32 API (accessible via - and the related headers), its DLL build will work - in any context. But if this library invokes standard C API, - things get more complicated. - - There is a single Win32 library in a Win32 system. Every - function in this library resides in a single DLL module, that - is safe to call from anywhere. On the other hand, there are - multiple versions of the C library, and each of them has its - own separate internal state. Standalone executables and user - DLLs that call standard C functions must link to a C run-time - (CRT) library, be it static or shared (DLL). Intermixing - occurs when an executable (not necessarily standalone) and a - DLL are linked to different CRTs, and both are running in the - same process. - - Intermixing multiple CRTs is possible, as long as their - internal states are kept intact. The Microsoft Knowledge Base - articles KB94248 "HOWTO: Use the C Run-Time" and KB140584 - "HOWTO: Link with the Correct C Run-Time (CRT) Library" - mention the potential problems raised by intermixing. - - If intermixing works for you, it's because your application - and DLLs are avoiding the corruption of each of the CRTs' - internal states, maybe by careful design, or maybe by fortune. - - Also note that linking ZLIB1.DLL to non-Microsoft CRTs, such - as those provided by Borland, raises similar problems. - - -11. Why are you linking ZLIB1.DLL to MSVCRT.DLL? - - - MSVCRT.DLL exists on every Windows 95 with a new service pack - installed, or with Microsoft Internet Explorer 4 or later, and - on all other Windows 4.x or later (Windows 98, Windows NT 4, - or later). It is freely distributable; if not present in the - system, it can be downloaded from Microsoft or from other - software provider for free. - - The fact that MSVCRT.DLL does not exist on a virgin Windows 95 - is not so problematic. Windows 95 is scarcely found nowadays, - Microsoft ended its support a long time ago, and many recent - applications from various vendors, including Microsoft, do not - even run on it. Furthermore, no serious user should run - Windows 95 without a proper update installed. - - -12. Why are you not linking ZLIB1.DLL to - <> ? - - - We considered and abandoned the following alternatives: - - * Linking ZLIB1.DLL to a static C library (LIBC.LIB, or - LIBCMT.LIB) is not a good option. People are using the DLL - mainly to save disk space. If you are linking your program - to a static C library, you may as well consider linking zlib - in statically, too. - - * Linking ZLIB1.DLL to CRTDLL.DLL looks appealing, because - CRTDLL.DLL is present on every Win32 installation. - Unfortunately, it has a series of problems: it does not - work properly with Microsoft's C++ libraries, it does not - provide support for 64-bit file offsets, (and so on...), - and Microsoft discontinued its support a long time ago. - - * Linking ZLIB1.DLL to MSVCR70.DLL or MSVCR71.DLL, supplied - with the Microsoft .NET platform, and Visual C++ 7.0/7.1, - raises problems related to the status of ZLIB1.DLL as a - system component. According to the Microsoft Knowledge Base - article KB326922 "INFO: Redistribution of the Shared C - Runtime Component in Visual C++ .NET", MSVCR70.DLL and - MSVCR71.DLL are not supposed to function as system DLLs, - because they may clash with MSVCRT.DLL. Instead, the - application's installer is supposed to put these DLLs - (if needed) in the application's private directory. - If ZLIB1.DLL depends on a non-system runtime, it cannot - function as a redistributable system component. - - * Linking ZLIB1.DLL to non-Microsoft runtimes, such as - Borland's, or Cygwin's, raises problems related to the - reliable presence of these runtimes on Win32 systems. - It's easier to let the DLL build of zlib up to the people - who distribute these runtimes, and who may proceed as - explained in the answer to Question 14. - - -13. If ZLIB1.DLL cannot be linked to MSVCR70.DLL or MSVCR71.DLL, - how can I build/use ZLIB1.DLL in Microsoft Visual C++ 7.0 - (Visual Studio .NET) or newer? - - - Due to the problems explained in the Microsoft Knowledge Base - article KB326922 (see the previous answer), the C runtime that - comes with the VC7 environment is no longer considered a - system component. That is, it should not be assumed that this - runtime exists, or may be installed in a system directory. - Since ZLIB1.DLL is supposed to be a system component, it may - not depend on a non-system component. - - In order to link ZLIB1.DLL and your application to MSVCRT.DLL - in VC7, you need the library of Visual C++ 6.0 or older. If - you don't have this library at hand, it's probably best not to - use ZLIB1.DLL. - - We are hoping that, in the future, Microsoft will provide a - way to build applications linked to a proper system runtime, - from the Visual C++ environment. Until then, you have a - couple of alternatives, such as linking zlib in statically. - If your application requires dynamic linking, you may proceed - as explained in the answer to Question 14. - - -14. I need to link my own DLL build to a CRT different than - MSVCRT.DLL. What can I do? - - - Feel free to rebuild the DLL from the zlib sources, and link - it the way you want. You should, however, clearly state that - your build is unofficial. You should give it a different file - name, and/or install it in a private directory that can be - accessed by your application only, and is not visible to the - others (e.g. it's not in the SYSTEM or the SYSTEM32 directory, - and it's not in the PATH). Otherwise, your build may clash - with applications that link to the official build. - - For example, in Cygwin, zlib is linked to the Cygwin runtime - CYGWIN1.DLL, and it is distributed under the name CYGZ.DLL. - - -15. May I include additional pieces of code that I find useful, - link them in ZLIB1.DLL, and export them? - - - No. A legitimate build of ZLIB1.DLL must not include code - that does not originate from the official zlib source code. - But you can make your own private DLL build, under a different - file name, as suggested in the previous answer. - - For example, zlib is a part of the VCL library, distributed - with Borland Delphi and C++ Builder. The DLL build of VCL - is a redistributable file, named VCLxx.DLL. - - -16. May I remove some functionality out of ZLIB1.DLL, by enabling - macros like NO_GZCOMPRESS or NO_GZIP at compile time? - - - No. A legitimate build of ZLIB1.DLL must provide the complete - zlib functionality, as implemented in the official zlib source - code.
