                                                                                      explain_adjtimex_or_die(3)

       The  explain_adjtimex_or_die  function  is  used  to  call  the  adjtimex(2)  system  call. On failure an
       explanation will be printed to stderr, obtained from  the  explain_adjtimex(3)  function,  and  then  the
       process terminates by calling exit(EXIT_FAILURE).

       The  explain_adjtimex_on_error  function  is  used  to  call  the  adjtimex(2) system call. On failure an
       explanation will be printed to stderr, obtained from the explain_adjtimex(3) function, but still  returns
       to the caller.

       data    The data, exactly as to be passed to the adjtimex(2) system call.

       The  explain_adjtimex_or_die  function  is  intended  to  be  used  in a fashion similar to the following
       example:
              int result = explain_adjtimex_or_die(data);

       The  explain_adjtimex_or_die  function  only returns on success, see adjtimex(2) for more information. On
       failure, prints an explanation and exits, it does not return.

       The explain_adjtimex_on_error function always returns the value return by the wrapped adjtimex(2)  system
       call.
