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>>.
