Linux线程库封装

一 MyThread.hpp

#pragma once
#include<pthread.h>
#include<iostream>
#include<unistd.h>
#include<string>
#include<ctime>

typedef void (*callback_t)();
static int num = 1;
//任务和线程绑定
class Thread
{
    static void* Routine(void *args)
    {
        Thread* ptr = static_cast<Thread*>(args);
        ptr->Entry();
        return nullptr;
    }
public:
    Thread(callback_t cb)
    :cb_(cb),tname_(""),start_time_stamp_(0),isrunning_(false)
    {}
    ~Thread()
    {}
    void Run()
    {
        tname_ = "thread-" + std::to_string(num);
        start_time_stamp_ = time(nullptr);
        isrunning_ = true;
        pthread_create(&tid_,nullptr,Routine,this);
    }
    void Join()
    {
        pthread_join(tid_,nullptr);
        isrunning_ = false;
    }
    void Entry()
    {
        cb_();
    }
    bool Isrunning()
    {
        return isrunning_;
    }
    std::string Name()
    {
        return tname_;
    }
    uint64_t StartTimeStamp()
    {
        return start_time_stamp_;
    }
private:
    pthread_t tid_;
    std::string tname_;
    callback_t cb_;//回调函数
    uint64_t start_time_stamp_;
    bool isrunning_;


};

二 测试

#include "MyThread.hpp"
#include <vector>
void task()
{
    while (1)
    {
        std::cout << "I am a task" << std::endl;
        sleep(1);
    }
}

int main()
{
    std::vector<Thread> threads;
    for (int i = 0; i < 10; ++i)
    {
        threads.push_back(Thread(task));
    }
    for (auto &t : threads)
    {
        t.Run();
    }
    for (auto &t : threads)
    {
        t.Join();
    }
}
// int main()
// {
//     Thread t1(task);
//     std::cout << "name:" << t1.Name() << " time:" << t1.StartTimeStamp()
//               << " isrun??  " << t1.Isrunning() << std::endl;
//     t1.Run();
//     std::cout << "name:" << t1.Name() << " time:" << t1.StartTimeStamp()
//               << " isrun??  " << t1.Isrunning() << std::endl;
//     t1.Join();
// }
