Function Documentation

void explain_getsockopt_or_die	(	int	fildes,
		int	level,
		int	name,
		void *	data,
		socklen_t *	data_size
	)

The explain_getsockopt_or_die function is used to call the getsockopt(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_getsockopt(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_getsockopt_or_die(fildes, level, name, data, data_size);

Parameters:

fildes	The fildes, exactly as to be passed to the getsockopt(2) system call.
level	The level, exactly as to be passed to the getsockopt(2) system call.
name	The name, exactly as to be passed to the getsockopt(2) system call.
data	The data, exactly as to be passed to the getsockopt(2) system call.
data_size	The data_size, exactly as to be passed to the getsockopt(2) system call.

Returns:

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