This function removes the buffer descriptor at the end of the chain of buffer descriptors for a given packet.
VOID NdisUnchainBufferAtBack( IN OUT PNDIS_PACKET Packet , OUT PNDIS_BUFFER * Buffer );
Parameters
- Packet
- Pointer to the packet descriptor.
- Buffer
- 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.
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 NdisQueryPacketfunction 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.
Requirements
Runs on Versions Defined in Include Link to Windows CE OS 2.0 and later Ndis.h Note This API is part of the complete Windows CE OS package as provided by Microsoft. The functionality of a particular platform is determined by the original equipment manufacturer (OEM) and some devices may not support this API.
