On failure an explanation will be printed to stderr, obtained from explain_wait3(3), and then the process terminates by calling exit(EXIT_FAILURE). This function is intended to be used in a fashion similar to the fol- lowing example: int pid = explain_wait3_or_die(status, options, rusage); 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.
