4.2 diprintf, vdiprintf—print to a file descriptor (integer only)

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.
