@chapter Files and Directories
@section Directories
@subsection Format of Directory Entries
@subsection Directory Operations
@example
struct dirent, Type, Unimplemented
opendir(), Function, Untested Implementation, assumes directory services
readdir(), Function, Untested Implementation, assumes directory services
readdir_r(), Function, Untested Implementation, assumes directory services
rewinddir(), Function, Untested Implementation, assumes directory services
closedir(), Function, Untested Implementation, assumes directory services
@end example
@section Working Directory
@subsection Change Current Working Directory
@example
chdir(), Function, Unimplemented
@end example
@subsection Get Working Directory Pathname
@example
getcwd(), Function, Untested Implementation, assumes directory services
@end example
@section General File Creation
@subsection Open a File
@example
open(), Function, Implemented, requires rework for directory services
O_RDONLY, Constant, Implemented
O_WRONLY, Constant, Implemented
O_RDWR, Constant, Implemented
O_APPEND, Constant, Implemented
O_CREAT, Constant, Implemented
O_DSYNC, Constant, Unimplemented
O_EXCL, Constant, Implemented
O_NOCTTY, Constant, Implemented
O_NONBLOCK, Constant, Implemented
O_RSYNC, Constant, Unimplemented
O_SYNC, Constant, Implemented
O_TRUNC, Constant, Implemented
@end example
NOTE: In the newlib fcntl.h, O_SYNC is defined only if _POSIX_SOURCE is
not defined. This seems wrong.
@subsection Create a New File or Rewrite an Existing One
@example
creat(), Function, Untested Implementation
@end example
@subsection Set File Creation Mask
@example
umask(), Function, Unimplemented
@end example
@subsection Link to a File
@example
link(), Function, Dummy Implementation
@end example
@section Special File Creation
@subsection Make a Directory
@example
mkdir(), Function, Unimplemented, assumes directory services
@end example
@subsection Make a FIFO Special File
@example
mkfifo(), Function, Unimplemented
@end example
@section File Removal
@subsection Remove Directory Entries
@example
unlink(), Function, Dummy Implementation
@end example
@subsection Remove a Directory
@example
rmdir(), Function, Unimplemented
@end example
@subsection Rename a File
@example
rename(), Function, Untested Implementation, assumes link/unlink
@end example
@section File Characteristics
@subsection File Characteristics Header and Data Structure
@example
struct stat, Type, Untested Implementation

S_ISREG(), Function, Implemented
S_TYPEISMQ(), Function, Unimplemented
S_TYPEISSEM(), Function, Unimplemented
S_TYPEISSHM(), Function, Unimplemented
@end example
@subsubsection <sys/stat.h> File Modes
@example
S_IRWXU, Constant, Implemented
S_IRUSR, Constant, Implemented
S_IWUSR, Constant, Implemented
S_IXUSR, Constant, Implemented
S_IRWXG, Constant, Implemented
S_IRGRP, Constant, Implemented
S_IWGRP, Constant, Implemented
S_IXGRP, Constant, Implemented
S_IRWXO, Constant, Implemented
S_IROTH, Constant, Implemented
S_IWOTH, Constant, Implemented
S_IXOTH, Constant, Implemented
S_ISUID, Constant, Implemented
S_ISGID, Constant, Implemented
@end example
@subsubsection <sys/stat.h> Time Entries
@subsection Get File Status
@example
stat(), Function, Partial Implementation
fstat(), Function, Partial Implementation
@end example
@subsection Check File Accessibility
@example
access(), Function, Unimplemented
@end example
@subsection Change File Modes
@example
chmod(), Function, Unimplemented
fchmod(), Function, Unimplemented
@end example
@subsection Change Owner and Group of a File
@example
chown(), Function, Unimplemented
@end example
@subsection Set File Access and Modification Times
@example
struct utimbuf, Type, Unimplemented
utime(), Function, Unimplemented
@end example
@subsection Truncate a File to a Specified Length
@example
ftruncate(), Function, Unimplemented
@end example

pathconf(), Function, Unimplemented
fpathconf(), Function, Unimplemented
_PC_LINK_MAX, Constant, Unimplemented
_PC_MAX_CANON, Constant, Unimplemented
_PC_MAX_INPUT, Constant, Unimplemented
_PC_MAX_INPUT, Constant, Unimplemented
_PC_NAME_MAX, Constant, Unimplemented
_PC_PATH_MAX, Constant, Unimplemented
_PC_PIPE_BUF, Constant, Unimplemented
_PC_ASYNC_IO, Constant, Unimplemented
_PC_CHOWN_RESTRICTED, Constant, Unimplemented
_PC_NO_TRUNC, Constant, Unimplemented
_PC_PRIO_IO, Constant, Unimplemented
_PC_SYNC_IO, Constant, Unimplemented
_PC_VDISABLE, Constant, Unimplemented
@end example
NOTE: The newlib unistd.h and sys/unistd.h are installed and the
include search patch is used to get the right one. There are
conflicts between the newlib unistd.h and RTEMS' version.' version.
