那位大侠可以帮小菜鸟看一下为什么会蓝屏的？？？
我只是想在PtReceive中看一下所得到的包～～
但一安装后就蓝屏了 说什麽physical memory 小菜一个，各位大侠可以看一下吗？ NDIS_STATUS PtReceive( IN NDIS_HANDLE ProtocolBindingContext, IN NDIS_HANDLE MacReceiveContext, IN PVOID HeaderBuffer, IN UINT HeaderBufferSize, IN PVOID LookAheadBuffer, IN UINT LookAheadBufferSize, IN UINT PacketSize ) /*++ Routine Description: LBFO - need to use primary for all receives Arguments: Return Value: --*/ { PADAPT pAdapt =(PADAPT)ProtocolBindingContext; PNDIS_PACKET MyPacket, Packet; NDIS_STATUS Status = NDIS_STATUS_SUCCESS; //--------------------------------------------------------- int size; PUCHAR pPacketContent; PUCHAR pBuf; UINT BufLength; MDL *pNext; UINT i; //--------------------------------------------------------- UINT workmode=0; //×Ô¼ºÓÃÀ´¶¨ÒåµÄ¹¤×÷ģʽ DbgPrint(\"===============>ÕýÔÚÔËÐÐÖеÄ×ÊÁÏ:PtReceive<===============\\n\"); if(!pAdapt->MiniportHandle) { Status = NDIS_STATUS_FAILURE; } else do { // // We should not be getting Receives on a Secondary, this is just specific to our LBFO driver // if(pAdapt->isSecondary) { DBGPRINT(\"PASSTHRU GETTING RECIEVES ON SECONDARY\\n\"); ASSERT(0); } // // If this was indicated by the miniport below as a packet, then get that packet pointer and indicate // it as a packet as well(with appropriate status).
