NET_BUFFER_PROTOCOL_RESERVED macro (ndis/nblaccessors.h)
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 an another driver has used ProtocolReserved, an intermediate driver cannot use it.
Requirements
| Requirement | Value |
|---|---|
| Minimum supported client | Supported in NDIS 6.0 and later. |
| Target Platform | Universal |
