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, 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.

RETURN VALUE

       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.

EXAMPLE

       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);
