       The  explain_ferror_or_die function is used to call the ferror(3) system call.  On failure an explanation
       will be printed to stderr, obtained from explain_ferror(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_ferror_or_die(fp);

       It is essential that this function cal be placed as close as possible to the I/O code that has caused the
       problem, otherwise intervening code could have altered the errno global variable.

       fp      The fp, exactly as to be passed to the ferror(3) system call.

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