C++ system time not clock time
WebThe // Posix clock CLOCK_REALTIME is defined as a 1/HZ clock, so by doing a // clock_getres on the realtime clock we can infer the scheduler quantum // and the minimimum sleep time for the system. This is most certainly NOT // going to be one nanosecond even though clock_nanosleep pretends it is. // // The reason this number is … WebIntroduction to clock () C++. clock () in C++ is defined as a function in the C++ header file that enables the developer to use the returned value of the approximate time for processing the program. This returned value from the function is then used by developers in order to find out the elapsed time. In order to achieve the functionality of ...
