                                                                                         explain_raise_or_die(3)

       The  explain_raise_or_die  function  is  used to call the raise(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_raise(3) function, and then the  process  terminates
       by calling exit(EXIT_FAILURE).

       The  explain_raise_on_error  function is used to call the raise(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_raise(3) function, but still returns to the caller.

       sig     The sig, exactly as to be passed to the raise(3) system call.

       The explain_raise_or_die function is intended to be used in a fashion similar to the following example:
              explain_raise_or_die(sig);

       explain_raise_or_die - send a signal to the caller and report errors

       The explain_raise_or_die function only returns on success, see raise(3) for more information. On failure,
       prints an explanation and exits, it does not return.

       The explain_raise_on_error function always returns the value return by the wrapped raise(3) system call.

raise(3)
               send a signal to the caller

       explain_raise(3)
               explain raise(3) errors

       exit(2) terminate the calling process
