WebJun 16, 2024 · (This is the counter you get from rdtsc, or __rdtsc () in C/C++, see this for more details, e.g. that on older CPUs it actually did count core clock cycles, and didn't tick during sleep states, so was less useful for wall-clock time.) Normal std::chrono implementations will use an OS-provided function like POSIX clock_gettime. WebAug 18, 2024 · Basic idea is to get current clock and add the required delay to that clock, till current clock is less than required clock run an empty loop. Here is implementation with a delay function. C. #include . #include . void delay (int number_of_seconds) {. int milli_seconds = 1000 * number_of_seconds;
