The \"clockid\"\nparameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME.\n\nThe timerfd_settime() API give new settings by the timerfd fd, by optionally\nretrieving the previous expiration time (in case the \"otmr\" parameter is not\nNULL).\n\nThe time value specified in \"utmr\" is absolute, if the TFD_TIMER_ABSTIME bit\nis set in the \"flags\" parameter. Otherwise it\u0027s a relative time.\n\nThe timerfd_gettime() API returns the next expiration time of the timer, or\n{0, 0} if the timerfd has not been set yet.\n\nLike the previous timerfd API implementation, read(2) and poll(2) are\nsupported (with the same interface).
