DWORD __stdcall QueDestroy(HANDLE hQue);
Before HNQueue object is destroyed, you should disconnect the queue from all adapters using it: call QueStop, then call AdpCloseAdapter function for each adapter, and then set ReceiveQueue [Get/Set] property to NULL for each adapter.
Also you have to return to queue all HNPacket objects belonging to it and obtained from the queue by QueGetFreeItem and QueGetFullItem functions or through OnPacketReceive event handler. For this purpose please use QueReturnFreeItem and QueReturnFullItem functions.
