       The  explain_getchar_or_die  function  is  used  to  call  the  getchar(3)  system  call.   On failure an
       explanation will be printed to stderr, obtained from explain_getchar(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 c = explain_getchar_or_die();

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