睡眠时间为毫秒 [英] Sleep for milliseconds

问题描述

我知道POSIX sleep（x）函数使程序休眠x秒。是否有一个函数可以使程序在C ++中休眠x 毫秒

I know the POSIX sleep(x) function makes the program sleep for x seconds. Is there a function to make the program sleep for x milliseconds in C++?

推荐答案

是毫秒的标准C API，所以（在Unix上）你必须解决 usleep ，它接受微秒：

Note that there is no standard C API for milliseconds, so (on Unix) you will have to settle for usleep, which accepts microseconds:

#include <unistd.h>

unsigned int microseconds;
...
usleep(microseconds);
