Back out previous and solve the problems a different way: move va_start/

va_end closer to the __vfprintf() call, free the buffer when __vfprintf() fails and don't bother trying to shrink the buffer with realloc() before returning it. Submitted by: bde

Sync with OpenBSD: avoid memory leak when __vfprintf() fails because it

runs out of memory, always call va_end.

Leave room for a trailing NUL not a NULL, that's not an ASCII character.

Basic support for wide character I/O: getwc(), fgetwc(), getwchar(),

2002-08-13T09:30:41Z

putwc(), fputwc(), putwchar(), ungetwc(), fwide().

Assume STDC, remove non-STDC code.

Fix the style of the SCM ID's.

I believe have made all of libc .c's as consistent as possible.

libc MT-safety, part 2.

Add a lock to FILE. flockfile and friends are now implemented (for the most part) in libc. flockfile_debug is implemented in libc_r; I suppose it's about time to kill it but will do it in a future commit. Fix a potential deadlock in _fwalk in a threaded environment. A file flag (__SIGN) was added to stdio.h that, when set, tells _fwalk to ignore it in its walk. This seemed to be needed in refill.c because each file needs to be locked when flushing. Add a stub for pthread_self in libc. This is needed by flockfile which is allowed by POSIX to be recursive. Make fgetpos() error return value (-1) match man page. Remove recursive calls to locked functions (stdio); I think I've got them all, but I may have missed a couple. A few K&R -> ANSI conversions along with removal of a few instances of "register". $Id$ -> $FreeBSD$ in libc/stdio/rget.c Not objected to: -arch, a few months ago

Replace memory leaking instances of realloc with non-leaking reallocf.

1998-09-16T04:17:47Z

In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes. Shouldn't impact anything, but...

Replace my original asprintf() and vasprintf() hacks with something

more cleanly integrated with stdio. This should be faster and cleaner since it doesn't memcpy() the data into a seperate buffer. This lets stdio allocate and manage the buffer and then hand it over to the user. Obtained from: Todd Miller via OpenBSD
