windows线程同步的几种方式

以下为main函数的测试代码 具体线程同步的实现代码请下载：https://github.com/kingsunc/ThreadSynchro

 

#include <stdio.h>  
#include <process.h>
#include "MyObject.h"
#include "MyCriticalSection.h"
#include "MyInterLock.h"
#include "MyRWLock.h"
#include "MySemaphore.h"
#include "MyMutex.h"
#include "MyEvent.h"

#define MY_NOSYNCHRO_TEST                // 不进行线程同步;

// 用户态-同步方式;
//#define MY_INTERLOCK_TEST                // 原子操作;
//#define MY_CRITICALSECTION_TEST        // 临界区;
//#define MY_SRWLOCK_TEST                // 读写锁;

// 内核态-同步方式;
//#define MY_SEMAPHORE_TEST                // 信号量;
//#define MY_MUTEX_TEST                    // 互斥量;
//#define MY_EVENT_TEST                    // 事件;

long g_lCount = 0;

#define THREAD_COUNT        10                // 线程数;
#define ACCESS_TIMES        100000            // 访问共享变量的次数，增大其值，增加数据竞争发生的可能性;
