NET_BUFFER_PROTOCOL_RESERVED macro (ndis/nblaccessors.h)

  • Article

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

Syntax

#define NET_BUFFER_PROTOCOL_RESERVED(_NB) ((_NB)->ProtocolReserved)

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.
