简单的AutoLock

Linux实现简单的AutoLock

AutoLock对象实例化时（构造函数）加锁，析构时释放锁。

#include <iostream>#include <pthread.h>using namespace std;class AutoLock{public:    AutoLock(pthread_mutex_t* mutex): m_mutex(mutex)    {        cout<<"lock"<<endl;        pthread_mutex_lock(m_mutex);    }    ~AutoLock()    {        cout<<"unlock"<<endl;        pthread_mutex_unlock(m_mutex);    }private:    pthread_mutex_t* m_mutex;};
