Function Documentation

int explain_socket_or_die	(	int	domain,
		int	type,
		int	protocol
	)

The explain_socket_or_die function is used to call the socket(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_socket(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:

 int fildes = explain_socket_or_die(domain, type, protocol);

Parameters:

domain	The domain, exactly as to be passed to the socket(2) system call.
type	The type, exactly as to be passed to the socket(2) system call.
protocol	The protocol, exactly as to be passed to the socket(2) system call.

Returns:

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