FUNCTION
<<diprintf>>, <<vdiprintf>>---print to a file descriptor (integer only)
INDEX
diprintf
INDEX
_diprintf_r
INDEX
vdiprintf
INDEX
_vdiprintf_r
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.
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>>.
