void detach();
|
(C++11 起) | |
从 thread 对象分离执行的线程,允许执行独立地持续。一旦线程退出,则释放所有分配的资源。
调用 detach
后, *this 不再占有任何线程。

joinable 为 false
若 joinable() == false 或错误发生时为 std::system_error 。
#include <iostream> #include <chrono> #include <thread> void independentThread() { std::cout << "Starting concurrent thread.\n"; std::this_thread::sleep_for(std::chrono::seconds(2)); std::cout << "Exiting concurrent thread.\n"; } void threadCaller() { std::cout << "Starting thread caller.\n"; std::thread t(independentThread); t.detach(); std::this_thread::sleep_for(std::chrono::seconds(1)); std::cout << "Exiting thread caller.\n"; } int main() { threadCaller(); std::this_thread::sleep_for(std::chrono::seconds(5)); }
可能的输出:
Starting thread caller. Starting concurrent thread. Exiting thread caller. Exiting concurrent thread.
等待线程完成其执行 (公开成员函数) |

检查线程是否可合并,即潜在地运行于平行环境中 (公开成员函数) |
