boost 实现读写锁

从网上看到有人发过，不过总有些小问题，小程序经过测试是可以的。

注：运行环境：VS2005，boost 1.46.1

#include <Windows.h>

#include <process.h>

#include <boost/thread/shared_mutex.hpp>

#include <boost/thread.hpp>

using namespace std;

typedef boost::shared_mutex rwmutex;

typedef boost::shared_lock<rwmutex> readLock;

typedef boost::unique_lock<rwmutex> writeLock;

rwmutex _rwmutex;

int cc_count = 0;

void __cdecl readOnly(LPVOID lpParameter)

{

readLock rdLock(_rwmutex);

//do something...

}

void __cdecl writeOnly(LPVOID lpParameter)

{

writeLock wlock(_rwmutex);

//do something...

}

int _tmain(int argc, _TCHAR* argv[])

{

for (int i=0;i<15;i++)

{

_beginthread(readOnly, 0, 0);

_beginthread(writeOnly, 0, 0);

}

Sleep(INFINITE);

return 0;

}
