  • std::detach()用法

     1 #include <chrono>
     2 #include <thread>
     3 
     4 void independentThread()
     5 {
     6   std::cout << "Starting concurrent thread.
    ";
     7   std::this_thread::sleep_for(std::chrono::seconds(2));
     8   std::cout << "Exiting concurrent thread.
    ";
     9 }
    10 
    11 void threadCaller()
    12 {
    13   std::cout << "Starting thread caller.
    ";
    14   std::thread t(independentThread);
    15   t.detach();
    16   std::this_thread::sleep_for(std::chrono::seconds(1));
    17   std::cout << "Exiting thread caller.
    ";
    18 }
    19 
    20 int main()
    21 {
    22   threadCaller();
    23   std::this_thread::sleep_for(std::chrono::seconds(5));
    24 }

    输出:

     1 #include <iostream>
     2 #include <chrono>
     3 #include <thread>
     4 using namespace std;
     5 
     6 void independentThread()
     7 {
     8   std::cout << "Starting concurrent thread.
    ";
     9   std::this_thread::sleep_for(std::chrono::seconds(10));
    10   std::cout << "Exiting concurrent thread.
    ";
    11 }
    12 
    13 void threadCaller()
    14 {
    15   std::cout << "Starting thread caller.
    ";
    16   std::thread t(independentThread);
    17   t.detach();
    18   std::this_thread::sleep_for(std::chrono::seconds(1));
    19   std::cout << "Exiting thread caller.
    ";
    20 }
