創建線程

HANDLE m_hThread;
m_hThread = CreateThread(NULL, 0, save_snapshot, (LPVOID)this, 0, &iThreadId);

開啟線程循環等待

DWORD WINAPI save_snapshot(LPVOID pVoid)
{while (true){//持續循環等待事件到達。接收到事件信號后才進入if。if (::WaitForSingleObject(m_event, INFINITE) == WAIT_OBJECT_0) {}}
}

發送事件

void SendSaveSnapEvent()
{SetEvent(m_event);  //發送事件，進入線程執行函數
}
