C++11 this_thread::sleep_for(10)

原文地址：http://www.cplusplus.com/reference/thread/this_thread/sleep_for/

function

std::this_thread::sleep_for

template 
  void sleep_for (const chrono::duration& 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"<

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

// this_thread::sleep_for example #include // std::cout, std::endl #include // std::this_thread::sleep_for #include // 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).
