最近看到好多人在问,c/c++中的sleep函数是秒级的,能不能实现毫秒级的呢?当然很简单,我的写法如下
#include <stdio.h>
#include <sys/select.h>
static void sleep_ms(unsigned int secs)
{
struct timeval tval;
tval.tv_sec=secs/1000;
tval.tv_usec=(secs*1000)%1000000;
select(0,NULL,NULL,NULL,&tval);
}
就这么简单,拿去用吧,开发愉快!原文地址:http://blog.csdn.net/guo_hongjun1611/article/details/40781533
