BOOL CNdisApi::ReadPackets ( PETH_M_REQUEST pPacket );
TRUE if call was successful,
Pointer to the user allocated and initialized ETH_M_REQUEST structure.
The following fields of ETH_M_REQUEST must be initialized:
ETH_M_REQUEST::hAdapterHandlemust be set to the interface handle (obtained via call to CNdisApi::GetTcpipBoundAdaptersInfo). The packets will be extracted from the network interface associated packet queue. Remember that packets queued only when network interface is in the filter mode.
ETH_M_REQUEST::dwPacketsNumbermust be set to a number of entries in
ETH_M_REQUEST::EthPacket[i].Buffermust point to the user allocated INTERMEDIATE_BUFFER structure
The following fields of the ETH_M_REQUEST and INTERMEDIATE_BUFFER are initialized by helper driver in case of success:
ETH_M_REQUEST::dwPacketSuccesscontains number of packets returned by driver
INTERMEDIATE_BUFFER::m_IBuffercontains Ethernet packet
INTERMEDIATE_BUFFER::m_Lengthcontains the actual length of the packet
INTERMEDIATE_BUFFER::m_Flagsis a combination of
NDIS_FLAGS_XXX(defined in ndis.h). These flags are copied from the
PACKET_FLAG_ON_SENDif packet goes from MSTCP to network interface, or
This member calls the filter driver with
IOCTL_NDISRD_READ_PACKETS control code (see details below).
