NdisUnchainBufferAtBack (Windows Embedded CE 6.0)

  • Статья

1/6/2010

This function removes the buffer descriptor at the end of the chain of buffer descriptors for a given packet.

Syntax

VOID NdisUnchainBufferAtBack(
  PNDIS_PACKET Packet,
  PNDIS_BUFFER* Buffer
);

Parameters

  • Packet
    [in, out] Pointer to the packet descriptor.
  • Buffer
    [out] Pointer to a caller-supplied variable in which this function returns a pointer to the removed buffer descriptor. If no buffer is chained to the specified packet, this variable is set to NULL.

Return Value

None.

Remarks

This function returns a pointer to the buffer descriptor that it removed from the buffer descriptor chain of 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.

Requirements

Header ndis.h
Windows Embedded CE Windows CE .NET 4.0 and later
