Function Documentation

int explain_fcntl_or_die	(	int	fildes,
		int	command,
		long	arg
	)

The explain_fcntl_or_die function is used to call the fcntl(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_fcntl(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_fcntl_or_die(fildes, command, arg);

Parameters:

fildes	The fildes, exactly as to be passed to the fcntl(2) system call.
command	The command, exactly as to be passed to the fcntl(2) system call.
arg	The arg, exactly as to be passed to the fcntl(2) system call.

Returns:

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