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 adjtime(2) smoothly tune kernel clock explain_adjtime(3) explain adjtime(2) errors exit(2) terminate the calling process COPYRIGHT libexplain version 1.3 Copyright (C) 2009 Peter Miller explain_adjtime_or_die(3)
