示例1: ThreadExecute
//
// ThreadPool's thread start routine
// - All the worker threads will start with this routine
// - the parameter passed to this thread start routine is "WorkThreadParam"
// It has
// threadWorkFunction :- thread work function;
// threadWorkParam :- thread param for the "threadWorkFunction"
// tPool :- thread pool object itself
//
DWORD WINAPI ThreadPool::ThreadExecute(LPVOID param)

PrdWorkUnit work;

return (DWORD)E_INVALIDARG;
}
WorkThreadParam* wParam = (WorkThreadParam*)param;
ThreadPool* tp = (ThreadPool*)wParam->tPool;
OS_OUTPUT_FORMAT_DEBUG_LOG(OS_DEBUG_LOG_DEBUG, L"Thread (%d) Created", GetCurrentThreadId());
// the worker cannot be assigned empty work..
// ThreadPool::fetchwork() will return false on DUMMY work;
// DUMMY work is used to request the thread to terminate.
