Sending Data (NDIS 5.1)

  • Article

Note   NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.

A connectionless miniport driver can have either of two functions for sending packets:

  • MiniportSendPackets

    NDIS passes MiniportSendPackets one or more packets at a time as an array of pointers to the packet descriptors.

  • MiniportSend

    NDIS always passes MiniportSend a single packet descriptor at a time.

A connection-oriented miniport driver must have a MiniportCoSendPacketsfunction to send packets. NDIS passes MiniportCoSendPacketsone or more packets at a time as an array of pointers to the packet descriptors.

For an overview of multipacket sends from connectionless and connection-oriented drivers, see Multipacket Sends.

For an overview of single-packets sends from connectionless drivers, see Single-Packet Sends.
