NdisChainBufferAtFront function

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 x has been deprecated and is superseded by NDIS 6.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.

NdisChainBufferAtFront links a given buffer descriptor to the head of the buffer-descriptor chain attached to a packet descriptor.

Syntax


VOID NdisChainBufferAtFront(
  _Inout_  PNDIS_PACKET Packet,

);

Parameters

Pointer to the packet descriptor.

Buffer [in, out]

Remarks

NdisChainBufferAtFront links the given buffer descriptor at the head of the chain for the given packet.

It also resets the valid counts for the packet to FALSE, thereby forcing NdisQueryPacket to recalculate information about the given packet if it is called subsequently with that packet.
