SYNOPSIS
#include <stdio.h>
#include <stdarg.h>
int diprintf(int <[fd]>, const char *<[format]>, ...);
int vdiprintf(int <[fd]>, const char *<[format]>, va_list <[ap]>);
int _diprintf_r(struct _reent *<[ptr]>, int <[fd]>,
const char *<[format]>, ...);
int _vdiprintf_r(struct _reent *<[ptr]>, int <[fd]>,
const char *<[format]>, va_list <[ap]>);
DESCRIPTION
<<diprintf>> and <<vdiprintf>> are similar to <<dprintf>> and <<vdprintf>>,
except that only integer format specifiers are processed.
Add support for asnprintf, and improve *printf documentation. * libc/stdio/Makefile.am (ELIX_SOURCES): Rename... (ELIX_2_SOURCES): ...to this. (ELIX_4_SOURCES): Add new variable. Build asnprintf. (GENERAL_SOURCES): Move dprintf to ELIX_4_SOURCES. (CHEWOUT_FILES): Include diprintf in documentation. * libc/stdio/Makefile.in: Regenerate. * libc/stdio/diprintf.c: Improve documentation. * libc/stdio/dprintf.c: Likewise. * libc/stdio/siprintf.c: Likewise. * libc/stdio/sprintf.c: Likewise. * libc/stdio/vfprintf.c: Likewise. * libc/stdio/viprintf.c: Likewise. * libc/stdio/vsniprintf.c: Consolidate documentation. * libc/stdio/asiprintf.c: Refer to documentation. * libc/stdio/asprintf.c: Likewise. * libc/stdio/fiprintf.c: Likewise. * libc/stdio/fprintf.c: Likewise. * libc/stdio/iprintf.c: Likewise. * libc/stdio/printf.c: Likewise. * libc/stdio/sniprintf.c: Likewise. * libc/stdio/vdiprintf.c: Likewise. * libc/stdio/vdprintf.c: Likewise. * libc/stdio/vsiprintf.c: Likewise. * libc/stdio/fvwrite.c (__sfvwrite_r): Handle asnprintf. * libc/stdio/asniprintf.c (asniprintf, _asniprintf_r): New file. * libc/stdio/asnprintf.c (asnprintf, _asnprintf_r): New file. * libc/stdio/vasniprintf.c (vasniprintf, _vasniprintf_r): New file. * libc/stdio/vasnprintf.c (vasnprintf, _vasnprintf_r): New file. * libc/stdio/vdprintf.c (_vdprintf_r): Rewrite to avoid malloc in typical case. * libc/stdio/vdiprintf.c (_vdiprintf_r): Likewise. * libc/include/stdio.h: Add prototypes for new functions; sort existing functions.

The functions <<_diprintf_r>> and <<_vdiprintf_r>> are simply
reentrant versions of the functions above.
RETURNS
Similar to <<dprintf>> and <<vdprintf>>.
PORTABILITY
This set of functions is an integer-only extension, and is not portable.
Supporting OS subroutines required: <<sbrk>>, <<write>>.
