FUNCTION
<<dprintf>>, <<vdprintf>>---print to a file descriptor
INDEX
dprintf
INDEX
_dprintf_r
INDEX
vdprintf
INDEX
_vdprintf_r
ANSI_SYNOPSIS
#include <stdio.h>
#include <stdarg.h>
int dprintf(int <[fd]>, const char *restrict <[format]>, ...);
int vdprintf(int <[fd]>, const char *restrict <[format]>,
va_list <[ap]>);
int _dprintf_r(struct _reent *<[ptr]>, int <[fd]>,
const char *restrict <[format]>, ...);
int _vdprintf_r(struct _reent *<[ptr]>, int <[fd]>,
const char *restrict <[format]>, va_list <[ap]>);
DESCRIPTION
<<dprintf>> and <<vdprintf>> allow printing a format, similarly to
<<printf>>, but write to a file descriptor instead of to a <<FILE>>
stream.
The functions <<_dprintf_r>> and <<_vdprintf_r>> are simply
reentrant versions of the functions above.
RETURNS
The return value and errors are exactly as for <<write>>, except that
<<errno>> may also be set to <<ENOMEM>> if the heap is exhausted.
PORTABILITY
This function is originally a GNU extension in glibc and is not portable.
Supporting OS subroutines required: <<sbrk>>, <<write>>.
