C++11this_threadsleep_for(10)

原文地址：http://www.cplusplus.com/reference/thread/this\_thread/sleep\_for/

function

std::this_thread::sleep_for

template <class Rep, class Period>
void sleep_for (const chrono::duration<Rep,Period>& rel_time);

Sleep for time span

Blocks execution of the calling thread during the span of time specified by rel_time.

阻塞当前线程rel_time的时间。

参考链接：http://www.cnblogs.com/jwk000/p/3560086.html一

The execution of the current thread is stopped until at least rel_time has passed from now. Other threads continue their execution.

从当前时间开始阻塞当前线程直到rel_time（一段时间）这段时间过去，其他线程依旧指向。

例子：

// thread::get_id / this_thread::get_id
#include // std::cout
#include // std::thread, std::thread::id, std::this_thread::get_id
#include // std::chrono::seconds
using namespace std;
void show(int n) {
if (n==5){
cout<<”start n=5”<<endl;
this_thread::sleep_for(chrono::seconds(5));
cout<<”sleep_for(chrono::seconds(5)) end”<<endl;
}
else{
cout<<”This is not 5”<<endl;
}
}

int main()
{
thread t(show,5);
thread t1(show,100);
t.join();
t1.join();
}

运行截图：

Parameters

rel_time

The time span after which the calling thread shall resume its execution.
Note that multi-threading management operations may cause certain delays beyond this.
duration is an object that represents a specific relative time.

线程阻塞的时间。

Return value

none

Example

// this_thread::sleep_for example
#include <iostream>       // std::cout, std::endl
#include <thread>         // std::this_thread::sleep_for
#include <chrono>         // std::chrono::seconds
 
int main() 
{
  std::cout << "countdown:\n";
  for (int i=10; i>0; --i) {
    std::cout << i << std::endl;
    std::this_thread::sleep_for (std::chrono::seconds(1));
  }
  std::cout << "Lift off!\n";

  return 0;
}

Edit & Run

Output (after 10 seconds):

countdown:
10
9
8
7
6
5
4
3
2
1
Lift off!

Exception safety

If the type of rel_time never throws exceptions (like the instantiations of duration in header ), this function never throws exceptions (no-throw guarantee).
