On failure an explanation will be printed to stderr, obtained from the explain_adjtimex(3) function, and then the process terminates by call- ing exit(EXIT_FAILURE).

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 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 fashion similar to the following example: int result = explain_adjtimex_or_die(data); SEE ALSO adjtimex(2) tune kernel clock explain_adjtimex(3) explain adjtimex(2) errors exit(2) terminate the calling process COPYRIGHT libexplain version 1.3 Copyright (C) 2009 Peter Miller explain_adjtimex_or_die(3)
