Linux clock id. Dec 8, 2019 · Linux環境で現在時刻を取得したり、処理時間を測定したりするために使用するclock_gettime()関数について確認したのでまとめました。 clock_gettime()関数 # include int clock_gettime(clockid Used for clock ID type in the clock and timer functions. It is defined as an arithmetic type. Alternatively, <sys/stat. It turns out that not only the numeric values are different across various systems, but symbolic names are also not the same for the same meaning. The example program below obtains the CPU-time clock ID of the process whose ID is given on the command line, and then uses clock_gettime (2) to obtain the time on that clock. According to POSIX, it shall be defined as an arithmetic type. 1-2001. Jun 26, 2015 · int clock_gettime(clockid_t clock_id, struct timespec *tp); Documentation for each system usually lists several symbolic names as possible clock_id values, but actual numeric values are never mentioned. #include int clock_getres(clockid_t clk_id, struct timespec *res); int clock_gettime(clockid_t clk_id, struct timespec *tp); int clock_settime(clockid_t clk_id, const struct timespec *tp); 15.
