在C ++中的睡眠功能 [英] Sleep function in C++

问题描述

我需要一个函数，如 Sleep（time）; 暂停程序X毫秒，但在C ++。

I need a function like Sleep(time); that pauses the program for X milliseconds, but in C++.

请写下要添加的标题和函数的签名。谢谢！

Please write which header to add and the function's signature. Thank you!

推荐答案

使用 std :: this_thread :: sleep_for

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

std::this_thread::sleep_for(timespan);

还有免费的 std :: this_thread :: sleep_until 。

在C ++ 11之前，C ++没有线程概念和睡眠功能，解决方案必然是平台依赖。以下是为Windows或Unix定义 sleep 函数的代码片段：

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 function for Windows or Unix:

#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

C ++ 11方法是使用 boost :: this_thread :: sleep 。

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