                                                                                       explain_waitpid_or_die(3)

       The  explain_waitpid_or_die  function  is  used  to  call  the  waitpid(2)  system  call.   On failure an
       explanation will be printed to stderr, obtained from explain_waitpid(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:
              explain_waitpid_or_die(pid, status, options);

       pid     The pid, exactly as to be passed to the waitpid(2) system call.

       status  The status, exactly as to be passed to the waitpid(2) system call.

       options The options, exactly as to be passed to the waitpid(2) system call.

       Returns:
               This function only returns on success.  On failure, prints an explanation and exits.
