#include<thread>{ScopeTimertimer;funcA();std::thread{funcB}.join();funcC();} 在上述程序中,我们刻意创建了一个线程来执行funcB(),而且调用.join()来等待线程的作业,即新分配的线程在funcB()执行完之后,主线程才会执行funcC()。我们观察输出可以看到,创建线程的开销很大,所以在日常使用中我们要尽量避免...

std::thread my_thread(my_function, 10); // 在主线程中输出一条消息 std::cout << "Main thread message" << std::endl; // 等待my_thread线程执行结束 my_thread.join(); return 0; } 这个程序会创建一个新的线程,并让它执行my_function函数。然后,主线程会输出一条消息,并等待新线程执行结束。
