This function links a specified buffer descriptor to the head of the buffer-descriptor chain attached to a packet descriptor.

At a Glance

Header file:	Ndis.h
Windows CE versions:	2.0 and later

Syntax

VOID NdisChainBufferAtFront( IN OUT PNDIS_PACKET Packet,
IN OUT PNDIS_BUFFER Buffer );

Parameters

Packet: Pointer to the packet descriptor.
Buffer: Pointer to the caller-supplied buffer descriptor to be added to the chain.

Remarks

This function links the specified buffer descriptor at the head of the chain for the specified packet. It also resets the valid counts for the packet to FALSE, thus forcing the NdisQueryPacket function to recalculate information about the specified packet if it is called subsequently with that packet.

A driver that calls this function can run at any IRQL, but usually runs at IRQL <=DISPATCH_LEVEL.
