ANSI_SYNOPSIS
|
|
#include <stdio.h>
|
|
#include <stdarg.h>
|
|
int dprintf(int <[fd]>, const char *<[format]>, ...);
|
|
int vdprintf(int <[fd]>, const char *<[format]>, va_list <[ap]>);
|
|
int _dprintf_r(struct _reent *<[ptr]>, int <[fd]>,
|
|
const char *<[format]>, ...);
|
|
int _vdprintf_r(struct _reent *<[ptr]>, int <[fd]>,
|
|
const char *<[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>>.
