Function Documentation

ssize_t XCALL_DEF() x_write_pipe	(	int	fd,
		const void *	buf,
		size_t	nbyte,
		int *	result
	)

Writes to a pipe.

Execution : deferred

Asynchronous failures : commit

Parameters:

[in]	fd	The file descriptor of the pipe's write end.
[in]	buf	The buffer that has the data to write.
[in]	nbyte	The number of bytes to write.
[out]	result	Where to store any asynchronous failures.

Returns:

The number of written bytes on success, or -1 if a synchronous failure occurred (in which case, errno is set appropriately).
