中间层发送问题:

 我在中间层发送，自己从一块buffer构建一个Packet，然后用NDISSend发送，但，每次在NDISSend执行时都会有0x000000d1的错误，
为什么？
请高手指教，代码如下:

long TransferBuffer(
IN  NDIS_HANDLE ProtocolBindingContext,
IN  PVOID pBuffer,
IN UINT PacketSize
)
{
int i ;
PNDIS_PACKET Packet;
NDIS_STATUS Status = NDIS_STATUS_SUCCESS;
PADAPT pAdapt =(PADAPT)ProtocolBindingContext;

PNDIS_BUFFER pNdisBuffer;

PETHHDR pEthHdr = (PETHHDR)pBuffer;
PIPHDR  pIPHdr  = (PIPHDR)(&((char *)pBuffer)[sizeof(ETHHDR)]);
PUDPHDR pUdpHdr = (PUDPHDR)(&((char*)pIPHdr)[sizeof(IPHDR)]);
PTRANSHDR pTransHdr = (PTRANSHDR)(&((char*)pUdpHdr)[sizeof(UDPHDR)]);

// pAdapt = pAdapt->pSecondaryAdapt;
pIPHdr->sourceIP = pIPHdr->destIP;
pUdpHdr->sourcePort = pUdpHdr->destPort;

(PTRANSIPINFO)(&((char*)pTransHdr)[sizeof(TRANSHDR)+i*sizeof(TRANSIPINFO)]);

pIPHdr->destIP = pIPHdr->sourceIP;
pUdpHdr->destPort = pUdpHdr->sourcePort;

NdisDprAllocatePacket(&Status,&Packet,pAdapt->SendPacketPoolHandle);
if (Status == NDIS_STATUS_SUCCESS)
{
NdisAllocateBuffer(
&Status,
&pNdisBuffer,
pAdapt->SendPacketPoolHandle,
Packet->ProtocolReserved,
PacketSize);

NdisChainBufferAtFront(
Packet,
pNdisBuffer);
NdisMoveMemory(
pNdisBuffer,
pBuffer,
PacketSize);
Packet->Private.TotalLength = PacketSize;
Packet->Private.Flags = 0;
Packet->Private.ValidCounts = 0;
Packet->Private.NdisPacketOobOffset = 0;
Packet->Private.NdisPacketFlags = NDIS_FLAGS_DIRECTED_PACKET;
NdisSend(&Status,pAdapt->SendPacketPoolHandle,Packet);

if(Status != NDIS_STATUS_PENDING)
{
NdisFreePacket(Packet);
NdisFreeMemory(pNdisBuffer, PacketSize, 0);  
}
}
return 0;
}

CSDN的也是你问的吗？

丢了一天的帖子。

1、NdisSend(&Status,pAdapt->SendPacketPoolHandle,Packet);
是pAdapt->BindingHandle

2、NdisAllocateBuffer(
&Status,
&pNdisBuffer,
pAdapt->SendPacketPoolHandle,
Packet->ProtocolReserved,
PacketSize);
如果你是要把pBuffer发送出去的话，改成
NdisAllocateBuffer(
&Status,
&pNdisBuffer,
// pAdapt->SendPacketPoolHandle,改成一个Buffer Pool Handle，而不是Packet Pool Handle
pBuffer,
PacketSize);

3、NdisFreeMemory(pNdisBuffer, PacketSize, 0);
pNdisBuffer是从allocate buffer而来，不是allocate memory！！


在ptsendcomplete还要有处理。
