Time Library
The time library is a key component of the new multithreading capabilities of C++. So you can put the current thread by std::this_thread::sleep_for(std::chrono::milliseconds(15) for 15 milliseconds to sleep, or you try to acquire a lock for 2 minutes: lock.try_lock_until(now + std::chrono::minutes(2)). Beside that, the chrono library makes it easy to perform simple performance tests:
// performanceMeasurement.cpp
...
#include <chrono>...
std::vector<int> myBigVec(10000000, 2011);
std::vector<int> myEmptyVec1;
auto begin= std::chrono::high_resolution_clock::now();
myEmptyVec1 = myBigVec;
auto end= std::chrono::high_resolution_clock::now() - begin;
auto timeInSeconds = std::chrono::duration<double>(end).count();
std::cout << timeInSeconds << std::endl; // 0.0150688800
The time library consists of the three components, time point, time duration and clock.
- Time point
- Time point is defined...
