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

Syntax

void 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.
