Function Documentation

void explain_sethostname_or_die	(	const char *	name,
		size_t	name_size
	)

The explain_sethostname_or_die function is used to call the sethostname(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_sethostname(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_sethostname_or_die(name, name_size);

Parameters:

name	The name, exactly as to be passed to the sethostname(2) system call.
name_size	The name_size, exactly as to be passed to the sethostname(2) system call.

Returns:

This function only returns on success, see sethostname(2) for more information. On failure, prints an explanation and exits, it does not return.
