For instance, if the clock hardware for CLOCK_REALTIMEuses a quartz crystal that oscillates at 32.768 kHz, then its resolution would be 30.518 microseconds, and ‘clock_getres (CLOCK_REALTIME, &r)’would set

Web15.2.2. clock_getres () を使用したクロック解決の比較 この clock_getres () 関数を使用すると、特定の POSIX クロックの解決が可能となります。 clock_getres () は、使用される POSIX クロックの ID と、結果が返される timespec 構造のポインターと同じ 2 つのパラメーターを clock_gettime () として使用します。 以下の関数を使用すると、 … WebThe function clock_getres () finds the resolution (precision) of the specified clock clockid, and, if res is non-NULL, stores it in the struct timespec pointed to by res . The resolution of clocks depends on the implementation and cannot be configured by a particular process. phfa board meetings

WebThe clock_gettime () and clock_settime () functions allow the calling process to retrieve or set the value used by a clock which is specified by clock_id . clock_id can be a value from one of 5 predefined values: CLOCK_REALTIME the system's real time (i.e. wall time) clock, expressed as the amount of time since the Epoch. WebThis clock represents the monotonic clock for the system. For this clock, the value returned by clock_gettime () represents the amount of time (in seconds and … Webclock_getres in the vDSO library has to preserve the same behaviour of posix_get_hrtimer_res(). In particular, posix_get_hrtimer_res() does: sec = 0; ns = hrtimer_resolution; and hrtimer_resolution depends on the enablement of the high resolution timers that can happen either at compile or at run time.
