1998-02-17Patch from Eric Norum <eric@skatter.usask.ca>:Joel Sherrill1-2/+5
I've gone through and cleaned up the TFTP driver so that it fits into the libio system. Here's the comment from the new driver: /* * Usage: * * To open `/bootfiles/image' on `hostname' for reading: * fd = open ("/TFTP/hostname/bootfiles/image", O_RDONLY); * * The `hostname' can be a symbolic name or four * dot-separated decimal values. * * To open a file on the host which supplied the BOOTP * information just leave the `hostname' part empty: * fd = open ("/TFTP//bootfiles/image", O_RDONLY); * */ You can `fopen' TFTP files the same way: fp = fopen (fullname, "r"); nread = fread (cbuf, sizeof cbuf[0], sizeof cbuf, fp); The diff's are included below. I've also modified the TFTP demo program and the bootstrap PROM example. They should be on my ftp site `soon'. The one thing I don't like is the way I had to do an end-run on the libio routines to get errno passed back from my driver to the application (since there are some errno codes that don't map to RTEMS status codes). My approach was to set errno in the driver and have the driver routine return an RTEMS status code that I `know' isn't in the errno_assoc[] in libio.c. Perhaps there should be an RTEMS_TRANPARENT_ERRNO status code (or something similar) which driver routines could return to indicate that the driver routine has set errno and that the libio routines shouldn't attempt to map the returned status code to errno. Actually, I think the entire I/O system needs looking at -- as you've already mentioned. The hacks I've dropped in to syscalls.c to make fstat work, for example, are *not* shining examples of good code......

the workspace by default.
1998-02-04Ralf Corsepius noticed that generally was spelled incorrectly.Joel Sherrill1-1/+1
1998-02-03Added call to libc_wrapup() in _exit. This fixes a problem whereJoel Sherrill1-0/+1
the atexit routines on the global reentrancy structure were not invoked. But it does not seem like a 100% correct solution.

1998-01-19Patch from Eric Norum:Joel Sherrill1-0/+1
With this in place, it is possible to fdopen a TCP stream socket and getc/fprintf/etc. on the STDIO stream!
1998-01-16Ralf Corsepius reported a number of missing CVS Id's:Joel Sherrill3-3/+3

I try to keep w\up with it. Now that you have asked -- I'll attach a list of files lacking an RCS-Id to this mail. This list has been generated by a little sh-script I'll also enclose.

1997-12-23Added CONFIGURE_GNAT_KEYS to correct the number of keys configuredJoel Sherrill1-12/+11
for GNAT. It was the number of Ada tasks when in fact the run-time only required a single key. Also added the CONFIGURE_MAXIMUM_FAKE_ADA_TASKS constant to account for resources allocated for each non-Ada task/thread which invokes the Ada run-time implicitly through an Ada call.
1997-12-22Corrected prototypes for all termios console write driver entries toJoel Sherrill2-3/+4

1997-12-06Moved include of rtems/score/cpu.h to make sure TRUE and FALSE were defined.Joel Sherrill1-2/+2
This simple error resulted in the wrong FP context structure being used for hardware contexts on the m68k. This was a difficult problem to find.

1997-09-19Bug fix from Eric Norum:Joel Sherrill1-1/+0
After weeks of trying to figure why my RTEMS/KASQ server crashes now and then I found a nasty bug I introduced in adding multiple-driver support to libio. The bug only affects `add-on' driver classes (like the networking code). Old-style file descriptors were not affected. The bug cleared 32 bytes of memory (unspecified location) whenever a `close' of a socket was performed! I was clearing an IOP I hadn't allocated -- and the pointer wasn't initiallized, either!
