ANSI_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 _vidprintf_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>>.
