C++11 多线程编程_c++多线程项目

一， 创建多线程

1. 通过线程函数创建

#include <iostream>
#include <thread>

void func1() 
{
    std::<< cout << "this is a thread function" << std::endl;
    
    return ;
}

void func2(int a, int b) 
{
    std::cout << "a + b = " << a + b << std::endl; 

    return ;
}

int main() 
{
    std::thread th1(func1);
    if (th1.joinable()) 
    {
        th1.join();
    }
    
    std::thread th2(func2, 1, 2);
    if (th2.joinable()) 
    {
        th2.join();
    }
    
    return 0;
}

2. Lambada表达式创建

#include <iostream>
#include <thread>

void func(int a, int b) 
{ 
    std::cout << "a + b = " << a + b << std::endl; 

    return ;
}

int main() 
{
    auto lambda = []() 
    {
        func(1, 2); 
    };
    
    std::thread th1(lambda);
    
    if (th1.joinable()) 
    {
        th1.join();
    }
    
    return 0;
}

3. 使用类对象的成员函数

#include <iostream>
#include <memory>
#include <thread>

class funcClass 
{
    void print() 
    { 
    	std::cout << "A\n"; 
   	}
};

int main() 
{
    std::shared_ptr<funcClass > tempClass = std::make_shared<funcClass >();
    
    auto func = [&]() 
    {
    	 tempClass->print(); 
   	 };
   	 
    std::thread th1(func);
    
    if (th1.joinable()) 
    {
        th1.join();
    }
    
    return 0;
}
