Function Documentation

FILE* explain_popen_or_die	(	const char *	command,
		const char *	flags
	)

The explain_popen_or_die function is used to call the popen(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_popen(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:

 FILE *fp = explain_popen_or_die(command, flags);

Parameters:

command	The command, exactly as to be passed to the popen(3) system call.
flags	The flags, exactly as to be passed to the popen(3) system call.

Returns:

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