# w-spin-mutex

#### 介绍
用c++语言实现的自旋锁

#### 使用说明

直接将WLockGuard.hpp和WSpinMutex.hpp这2个文件放到自己的工程里面即可，使用代码看main.cpp，和std锁的接口是一样的

```
#include "WLockGuard.hpp"
#include "WSpinMutex.hpp"
#include <thread>
#include <vector>

using namespace std;

WSpinMutex g_mutex;
int g_data = 0;

void test()
{
    WLockGuard<WSpinMutex> locker(&g_mutex);
    for(int i = 0; i < 100; i++)
    {
        g_data++;
    }
}

int main(int argc, char *argv[])
{
    vector<thread> threadList;
    for (int i = 0; i < 8; i++)
    {
        threadList.emplace_back(test);
    }

    for (int i = 0; i < 8; i++)
    {
        threadList[i].join();
    }

    std::cout << "g_data is " << g_data << std::endl;
    return 0;
}

```
