不定个数的c++函数指针

关于多线程下利用vector保存函数指针并调用的方法，这是一个最简单的函数指针调用实例，大家可以看到这样对于处理一些第一时间处理数据的业务非常合适，这样处理的实时性非常好，当然而且可以多个处理函数来处理数据，也可以将mytest这个class 封装起来，是外部使用的人不必关心内部如何产生数据的。外部直接

struct mystuct{int myInt;char myStr[100];};class mytest{private:static unsigned long WINAPI TestThread(LPVOID lpvoid); volatile unsigned long threadRun;int CreateTestThread();vector<void (*)(mystuct *pdata)> functionvector;HANDLE m_ExitEvent;public:mytest(void){}~mytest(void){}int AddFunctionAddr(void (*_ProcesseFunction)(mystuct *pdata));void initialize();void shutdown();};void mytest::initialize(){CreateTestThread();}void  mytest::shutdown(){InterlockedExchange(&threadRun,0);WaitForSingleObject(m_ExitEvent,INFINITE);ResetEvent(m_ExitEvent);CloseHandle(m_ExitEvent);}int mytest::AddFunctionAddr(void (*_ProcesseFunction)(mystuct *pdata)){functionvector.push_back(_ProcesseFunction);return 0;}unsigned long WINAPI  mytest::TestThread(LPVOID lpvoid){mytest* pMytest = (mytest*)lpvoid; int i =15;while(1){mystuct _mystuct;memset(_mystuct.myStr,0,100);memcpy(_mystuct.myStr,"月·小轩",sizeof("月·小轩"));_mystuct.myInt=i;if (0==pMytest->threadRun){break;}for (int i=0;i<(int)(pMytest->functionvector.size());i++){if (NULL!=(pMytest->functionvector[i])){(*(pMytest->functionvector[i]))(&_mystuct);}}i++;Sleep(1000);}SetEvent(pMytest->m_ExitEvent);return 0;}int mytest::CreateTestThread(){m_ExitEvent= CreateEvent(NULL,TRUE,FALSE,L"test_Eixt");InterlockedExchange(&threadRun,1);DWORD dwthreadID;HANDLE h_Handle= CreateThread(NULL,NULL,TestThread,this,0,&dwthreadID);if (NULL==h_Handle){CloseHandle(h_Handle);return 1;}CloseHandle(h_Handle);return 0;}void printFunction1(mystuct* data){int resultNumber = data->myInt;printf("%d\t",resultNumber);}void printFunction2(mystuct* data){printf("%s\t",data->myStr);}void main(){mytest* _mytest = new mytest();_mytest->AddFunctionAddr(printFunction1);_mytest->AddFunctionAddr(printFunction2);_mytest->initialize();system("pause");_mytest->shutdown();}
