date(1),adjtime(2),clock_getcpuclockid(3),ctime(3),pthread_getcpuclockid(3),timed(8) STANDARDS Theclock_gettime(),clock_settime(), andclock_getres() system calls conform to IEEE Std 1003.1b-1993 (“POSIX.1”). The clock IDsCLOCK_REALTIME_FAST,CLOCK_REALTIME_PRECISE,CLOCK_MONOTONIC...
The functions clock_gettime() and clock_settime() retrieve and set the time of the specified clock clockid. The res and tp arguments are timespec(3) structures. The clockid argument is the identifier of the particular clock on which to act. A clock may be system-wide and hence visible...

undefined reference to `clock_gettime' I've read that library specified by -lrt doesn't exist for the Android, and I've found posts other places claiming that folks are using clock_gettime() on Android projects, but I haven't been able to find the right library to link to for this....

--cpustats使实际CPU时间报告(不光是实际度量时间(wall time))出现在查询日志文件(每条查询输出一次)和状态报告(累加之后)中。这个选项依赖clock_gettime()系统调用,因此可能在某些系统上不可用。可以这样启动searchd: $ searchd --config /home/myuser/sphinx.conf --cpustats ...
在Ubuntu系统下,可以使用C语言编写一个简单的程序来测试usleep函数的准确性 #include<stdio.h> #include <unistd.h> #include <time.h> int main() { struct timespec start, end; long sleep_time = 100000; // 100ms // 获取开始时间 clock_gettime(CLOCK_MONOTONIC, &start); // 调用usleep函数 ...
