HOW TO SLEEP FOR IN C++

在使用C++11的时候，我需要对线程进行等待操作，下面有四种方法： 

1. Use usleep (POSIX)
2. Use Sleep (Windows)
3. Use Boost.Thread
4. Use std::this_thread::sleep_for (C++11)

Method 1: Use usleep (POSIX)

1 2 3 4 5 6

#include   int main() {     usleep(500); }

Method 2: Use Sleep (Windows)

1 2 3 4 5 6

#include   int main() {     Sleep(500); }

Method 3: Use Boost.Thread

1 2 3 4 5

#include int main() {     boost::this_thread::sleep(boost::posix_time::milliseconds(500)); }

Method 4: Use std::this_thread::sleep_for (C++11)

1 2 3 4 5 6 7

#include #include   int main() {     std::this_thread::sleep_for(std::chrono::milliseconds(500)); }
