根据工程需要，对相关方法进行了封装

///事件源[event_source(native)]class __declspec(dllexport)  CEventSource{public: CEventSource(); ~CEventSource();public: //生成事件 bool DoEvent(void* pPack,int nLength); //事件 __event bool Event(void* pEventData,int nLength);};///事件接收[event_receiver(native)]class __declspec(dllexport)  CEventReceiver{public: CEventReceiver(); ~CEventReceiver();public:    void HookEvent(CEventSource* pSource,pReceiveEventCallbackFun pReceiveEventCallbackFun,         void* pReceiveEventCallbackFunUser); void UnhookEvent(CEventSource* pSource); private: bool AccepEvent(void* pEventData,int nLength);private: //事件回调 pReceiveEventCallbackFun m_pEventDataCallbackFun; void* m_pEventDataCallbackFunUser; };

示例：

//提供应用层使用的回调static void ReceiveEventCallbackFun(void* pBuffer,int nBufferLen,void* pUser); //调用过程CEventSource* source = new CEventSource(); CEventReceiver* receiver = new CEventReceiver(); receiver->HookEvent(source,ReceiveEventCallbackFun,this); //构造测试数据 STestParam* temp = (STestParam*)Malloc(STestParamSize); temp->m_nType = 256; SafePrintf(temp->m_szInfo,256,"DoEvent: %d",temp->m_nType); //发送事件 source->DoEvent((void*)temp,STestParamSize); // Do somethingreceiver->UnhookEvent(source); delete(receiver);receiver = NULL;delete(source); source = NULL;
