Function Documentation

int explain_wait3_or_die	(	int *	status,
		int	options,
		struct rusage *	rusage
	)

The explain_wait3_or_die function is used to call the wait3(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_wait3(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:

 pid_t pid = explain_wait3_or_die(status, options, rusage);

Parameters:

status	The status, exactly as to be passed to the wait3(2) system call.
options	The options, exactly as to be passed to the wait3(2) system call.
rusage	The rusage, exactly as to be passed to the wait3(2) system call.

Returns:

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