標準庫中無該函式

但在某些編譯系統中有，在有些系統庫中有，要根據你那邊的環境而定。 如:

linux中有，unsigned int sleep(unsigned int seconds)，傳入掛起時間，成功返回0，不成功則返回餘下的秒數。 windows系統中有Sleep函式（注意大寫），void Sleep(DWORD dwMilliseconds); 提供掛起的毫秒數。

例如：

#include<iostream> #include<windows.h> using namespace std; int main() { Sleep(3000);//暫停3秒  S要大寫 return 0; }

Use std::this_thread::sleep_for:

std::chrono::milliseconds timespan(111605);// or whatever

std::this_thread::sleep_for(timespan);

There is also the complimentary std::this_thread::sleep_until.

Prior to C++11, C++ had no thread concept and no sleep capability, so your solution was necessarily platform dependent. Here's a snippet that defines a sleep

#ifdef _WIN32
    #include<windows.h>void sleep(unsigned milliseconds){Sleep(milliseconds);}#else#include<unistd.h>void sleep(unsigned milliseconds){
        usleep(milliseconds *1000);// takes microseconds}#endif

But a much simpler pre-C++11 method is to use boost::this_thread::sleep
