                                                                                         explain_wait3_or_die(3)

       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 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 following 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.
