  • Article

3/12/2014

This is a macro that NDIS drivers use to access the MiniportReserved member of a NET_BUFFER structure.

Syntax

NET_BUFFER_MINIPORT_RESERVED(_NB)

Parameters

  • _NB
    A pointer to a NET_BUFFER structure.

Return Value

NET_BUFFER_MINIPORT_RESERVED returns a pointer to the start of the MiniportReserved member of the specified NET_BUFFER structure.

Remarks

Miniport drivers and NDIS intermediate drivers can use MiniportReserved for their own purposes. Miniport drivers typically use MiniportReserved to maintain NET_BUFFER structure context information for outstanding transfers.

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