This is a macro that NDIS drivers use to get the ProtocolReserved member of a NET_BUFFER structure.

Syntax

NET_BUFFER_PROTOCOL_RESERVED(_NB)

Parameters

  • _NB
    A pointer to a NET_BUFFER structure.

Return Value

NET_BUFFER_PROTOCOL_RESERVED returns the value of the ProtocolReserved member of the specified NET_BUFFER structure.

Remarks

Protocol drivers and NDIS intermediate drivers can use this area for their own purposes. Protocol drivers typically use ProtocolReserved to maintain NET_BUFFER structure context information for outstanding transfers.

Note   Only one driver can use ProtocolReserved. Therefore, if another driver has used ProtocolReserved, an intermediate driver cannot use it.
