19 SYNOPSIS
20 #include <stdio.h>
21 #include <stdarg.h>
22 int diprintf(int <[fd]>, const char *<[format]>, ...);
23 int vdiprintf(int <[fd]>, const char *<[format]>, va_list <[ap]>);
24 int diprintf( int <[fd]>,
25 const char *<[format]>, ...);
26 int vdiprintf( int <[fd]>,
27 const char *<[format]>, va_list <[ap]>);

29 DESCRIPTION
30 <<diprintf>> and <<vdiprintf>> are similar to <<dprintf>> and <<vdprintf>>,
31 except that only integer format specifiers are processed.
32
33 The functions <<_diprintf_r>> and <<_vdiprintf_r>> are simply
34 reentrant versions of the functions above.
35
36 RETURNS
37 Similar to <<dprintf>> and <<vdprintf>>.
38
39 PORTABILITY
40 This set of functions is an integer-only extension, and is not portable.
41
42 Supporting OS subroutines required: <<sbrk>>, <<write>>.
