facc67676f mdoc(7) police: Deal with self-xrefs. 2002-12-24 13:41:48 +00:00
Tim J. Robbins
4aca04ee5c Document the fact that the printf() family of functions return negative
values (EOF in our case) on error, and some of the possible errno values
in an Errors section.

37d2356335 Write the message to stderr, not file descriptor 2, so that perror()

a207a8e3f1 Use strerror_r() to format the error message so that strerror()'s static
buffer does not get clobbered.

ISO/IEC 9899:1999 7.21.6.2 3:
"The implementation shall behave as if no library function calls the
strerror function."

ae82896268 Consistently mark std(in|out|err) with .Dv, because that's how they
are marked up in stdio(3), and because they are defined expressions
of type "FILE *".

cf04ed1bdf bde points out that the LIBC_MAJOR macro doesn't exist and requests
that we not use it here.  In its place I've put a comment about the
current state of play.

c906b66373 Restore Peter's version of static __sF. There's too much pain for it
to be static for 5.0.  I may remove this for 5.1 or 5.2.  No more
binaries or libarires will be generated with __sF starting as of
yesterday.  Originally the plan had been to eliminate this for 5.0,
but we didn't get the __std{in,out,err}p changes merged into -stable
until yesterday (rather than in September 2001 like it should have
been).  Given that didn't happen on time, we can't do the other part
of the scheme now.

# Please do not change this without talking to me first.

bd25c6f476 The field width for single-byte string conversions (%c, %s, %[) is the
maximum number of bytes that may be stored in the array, not the maximum
number of wide characters to read. The wording of the standard unfortunately
does not make this clear.

3619568a64 Remove masking macros for getwc(), putwc(), putwchar() and getwchar().
Although there was nothing wrong with getwc() and putwc(), getwchar()
and putwchar() assumed that <stdio.h> had been included before <wchar.h>,
which is not allowed by the standard.

344141d1fd 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.

89265cb899 Remove an unneeded call to _sfrefill() that was missed in the conversion
from vfscanf() to vfwscanf(). It doesn't hurt to have it there, but it's
redundant since __fgetwc() will refill the buffer if it needs to.
