Linux多线程及临界区编程例解

先贴示范代码：

// --------------------tmutex.h开始------------------------------
// 实现linux的互斥量c++封装

#ifndef TMUTEX_H
#define  TMUTEX_H

#include  < pthread.h >

// 线程互斥量
struct  ThreadMutex
... {
        ThreadMutex()
        ...{
                pthread_mutex_init(&mtx,NULL);
        }

        ~ThreadMutex()
        ...{
                pthread_mutex_destroy( &mtx );
        }

        inline void lock()
        ...{
                pthread_mutex_lock( &mtx );
        }

        inline void unlock()
        ...{
                pthread_mutex_unlock( &mtx );
        }
