explain_adjtimex_or_die(3) Library Functions Manual explain_adjtimex_or_die(3)

NAME
       explain_adjtimex_or_die - tune kernel clock and report errors

SYNOPSIS
       #include	<libexplain/adjtimex.h>
       int explain_adjtimex_or_die(struct timex	*data);
       int explain_adjtimex_on_error(struct timex *data);

DESCRIPTION
       The  explain_adjtimex_or_die  function  is used to call the adjtimex(2)
       system call. On failure an explanation will be printed to  stderr,  ob-
       tained from the explain_adjtimex(3) function, and then the process ter-
       minates 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,  ob-
       tained  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.

RETURN VALUE

       timex(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.

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

SEE ALSO
