# If I've done so improperly on a file, please let me know.

92a5b2ee71 Rename cantwrite() to prepwrite(). The latter is less confusing,
since the macro isn't really a predicate, and it has side-effects.
Also, don't set errno if prepwrite() fails, since this is done in
prepwrite() now.

1b629e865e If handed a file pointer we can't write to, set errno properly to EBADF
in order to get SUSv2 conformant behavior in higher level calls like
fputs() and puts().

333fc21e3c Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

5e00917d95 Re-arrange my funopen(3) fix to minimize differences with original stdio code,
no functional changes.

Add fp->_offset optimization in _SAPP+_SOPT case

924888f977 Move all stdio internal flags processing and setting out of __sread(),
__swrite() and __sseek() to higher level. According to funopen(3) they all
are just wrappers to something like standard read(2), write(2) and
lseek(2), i.e. must not touch stdio internals because they are replaceable
with any other functions knows nothing about stdio internals. See example
of funopen(3) usage in sendmail sources f.e.

NOTE: this is original stdio bug, not result of my range checkin added.

d201fe46e3 Remove _THREAD_SAFE and make libc thread-safe by default by
adding (weak definitions to) stubs for some of the pthread
functions.  If the threads library is linked in, the real
pthread functions will pulled in.

Use the following convention for system calls wrapped by the
threads library:
	__sys_foo - actual system call
	_foo - weak definition to __sys_foo
	foo - weak definition to __sys_foo

Change all libc uses of system calls wrapped by the threads
library from foo to _foo.  In order to define the prototypes
for _foo(), we introduce namespace.h and un-namespace.h
(suggested by bde).  All files that need to reference these
system calls, should include namespace.h before any standard
includes, then include un-namespace.h after the standard
includes and before any local includes.  <db.h> is an exception
and shouldn't be included in between namespace.h and
un-namespace.h  namespace.h will define foo to _foo, and
un-namespace.h will undefine foo.

Try to eliminate some of the recursive calls to MT-safe
functions in libc/stdio in preparation for adding a mutex
to FILE.  We have recursive mutexes, but would like to avoid
using them if possible.

Remove uneeded includes of <errno.h> from a few files.

Add $FreeBSD$ to a few files in order to pass commitprep.

e8420087b0 Replace memory leaking instances of realloc with non-leaking reallocf.
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...

64a965e707 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.

2) Optimize string buffer copy to call memcpy() and update pointers

a65a537cb1 Remove wrong comment about snprintf:
"return the number of bytes needed, rather the number used"

According to Single Unix specs:

Upon successful completion, these functions return the number of bytes
transmitted excluding the terminating null

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

Added $Id$'s to files that were lacking them (gpalmer), made some
cosmetic changes to conform to style guidelines (bde) and checked
against NetBSD and Lite2 to remove unnecessary divergences (hsu, bde)

One last code cleanup:-

Removed spurious casts in fseek.c and stdio.c.
Added missing function argument in fwalk.c.
Added missing header include in flags.c and rget.c.
Put in casts where int's were being passed as size_t's.
Put in missing prototypes for static functions.
Changed second args of __sflags() inflags.c and writehook() in vasprintf.c
from char * to const char * to conform to prototypes.

This directory now compiles with no warnings with -Wall under
gcc-2.6.3 and with considerably less warnings than before with the
ultra-pedantic script I used for testing. (Most of the remaining ones
are due to const poisoning).

b83100194d Code cleanup:-
The usual stuff, adding missing function prototypes, argument types,
return values, etc. In mktemp.c, convert pid from u_int to pid_t, and
get rid of "extern int errno".
