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
       The explain_adjtimex_or_die function only returns on success, see  adj-
       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);
