Function Documentation

void explain_listen_or_die	(	int	fildes,
		int	backlog
	)

The explain_listen_or_die function is used to call the listen(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_listen(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

This function is intended to be used in a fashion similar to the following example:

 explain_listen_or_die(fildes, backlog);

Parameters:

fildes	The fildes, exactly as to be passed to the listen(2) system call.
backlog	The backlog, exactly as to be passed to the listen(2) system call.

Returns:

This function only returns on success. On failure, prints an explanation and exits, it does not return.
