safe_pipe_write - Writes to pipe with trap for SIGPIPE

SYNOPSIS

#include "l/l_sys_io.h"

int safe_pipe_write
(
	int des,
	const void *buff,
	size_t num_bytes
);

PARAMETERS

int des
File descriptor
const void *buff
Location of bytes to write.
size_t num_bytes
Number of bytes to write.

DESCRIPTION

This routine writes to a pipe, trapping SIGPIPE so that if raised, error is returned. Otherwise, this routine is the same as kjb_write. This routine can be safely called with a descriptor for any type of file, but if the type of file is known not to be a pipe, then there is nothing to be gained over kjb_write.

RETURNS

On success safe_pipe_write returns the number of bytes written. On failure ERROR is returned and an error message is set.

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
