                                                                                        explain_fseeko_or_die(3)

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

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

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

       offset  The offset, exactly as to be passed to the fseeko(3) system call.

       whence  The whence, exactly as to be passed to the fseeko(3) system call.

       The explain_fseeko_or_die function is intended to be used in a fashion similar to the following example:
              explain_fseeko_or_die(fp, offset, whence);

       explain_fseeko_or_die - seek to or report file position and report errors

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

       The explain_fseeko_on_error function always returns the value return  by  the  wrapped  fseeko(3)  system
       call.
