explain_adjtime_or_die(3)  Library Functions Manual  explain_adjtime_or_die(3)

NAME
       explain_adjtime_or_die -	smoothly tune kernel clock and report errors

SYNOPSIS
       #include	<libexplain/adjtime.h>
       void explain_adjtime_or_die(const struct	timeval	*delta,	struct timeval
       *olddelta);
       int  explain_adjtime_on_error(const  struct  timeval   *delta,	struct
       timeval *olddelta);

DESCRIPTION
       The explain_adjtime_or_die function is used to call the adjtime(2) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from  the  explain_adjtime(3) function, and then	the process terminates
       by calling exit(EXIT_FAILURE).

       The explain_adjtime_on_error function is	used to	 call  the  adjtime(2)
       system  call.  On failure an explanation	will be	printed	to stderr, ob-
       tained from the explain_adjtime(3) function, but	still returns  to  the
       caller.

       delta   The  delta,  exactly  as	 to be passed to the adjtime(2)	system
	       call.

       olddelta
	       The olddelta, exactly as	to be passed to	the adjtime(2)	system
	       call.

RETURN VALUE
       The  explain_adjtime_or_die  function only returns on success, see adj-
       time(2) for more	information. On	failure, prints	an explanation and ex-
       its, it does not	return.

       The  explain_adjtime_on_error  function always returns the value	return
       by the wrapped adjtime(2) system	call.

EXAMPLE
       The explain_adjtime_or_die function is intended to be used in a fashion
       similar to the following	example:
	      explain_adjtime_or_die(delta, olddelta);

SEE ALSO

       explain_adjtime(3)
	       explain adjtime(2) errors

       exit(2) terminate the calling process
