FUNCTION

<>, <>---print to a file descriptor

INDEX

	dprintf

INDEX

	_dprintf_r

INDEX

	vdprintf

INDEX

	_vdprintf_r

ANSI_SYNOPSIS

	#include 

	#include 

	int dprintf(int <[fd]>, const char *restrict <[format]>, ...);

	int vdprintf(int <[fd]>, const char *restrict <[format]>,

			va_list <[ap]>);

	int _dprintf_r(struct _reent *<[ptr]>, int <[fd]>,

			const char *restrict <[format]>, ...);

	int _vdprintf_r(struct _reent *<[ptr]>, int <[fd]>,

			const char *restrict <[format]>, va_list <[ap]>);

DESCRIPTION

<> and <> allow printing a format, similarly to

<>, but write to a file descriptor instead of to a <>

stream.

The functions <<_dprintf_r>> and <<_vdprintf_r>> are simply

reentrant versions of the functions above.

RETURNS

The return value and errors are exactly as for <>, except that

<> may also be set to <> if the heap is exhausted.

PORTABILITY

This function is originally a GNU extension in glibc and is not portable.

Supporting OS subroutines required: <>, <>.
