std::thread 各种构造函数例子如下(参考): #include <iostream> #include <utility> #include <thread> #include <chrono> void f1(int n) { for (int i = 0; i < 5; ++i) { std::cout << "Thread 1 executing\n"; ++n; std::this_thread::sleep_for(std::chrono::milliseconds(10)); ...
void countnumber(int id, unsigned int n) { for (unsigned int i = 1; i <= n; i++); cout << "Thread " << id << " finished!" << endl; } int main() { thread th[10]; for (int i = 0; i < 10; i++) th[i] = thread(countnumber, i, 100000000); ...
<thread>头文件主要声明了std::thread类,另外在std::this_thread命名空间中声明了get_id,yield,sleep_until以及sleep_for等辅助函数,本章稍微会详细介绍std::thread类及相关函数。 std::thread类摘要 std::thread代表了一个线程对象,C++11 标准声明如下: ...
C++11 之前，C++ 语言没有对并发编程提供语言级别的支持，这使得我们在编写可移植的并发程序时，存在诸多...

使用std::thread时,需要包含头文件,并且线程对象可以使用构造函数初始化。例如: ```cpp #include #include void threadFunc() { std::cout << "Hello from thread" << std::this_thread::get_id() << std::endl; } int main() { std::thread threadObj(threadFunc); // 等待线程执行完成 thread...
