FUNCTION

<<diprintf>>, <<vdiprintf>>---print to a file descriptor (integer only)

INDEX

        diprintf

INDEX

        _diprintf_r

INDEX

        vdiprintf

INDEX

        _vdiprintf_r

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 _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>>.
