NET_BUFFER_SHARED_MEM_OFFSET macro

The NET_BUFFER_SHARED_MEM_OFFSET macro gets the shared memory offset from a NET_BUFFER_SHARED_MEMORY structure.

Syntax

void NET_BUFFER_SHARED_MEM_OFFSET(
   _SHI
);

Parameters

_SHI

A pointer to a NET_BUFFER_SHARED_MEMORY structure.

Return Value

NET_BUFFER_SHARED_MEM_OFFSET returns a ULONG value that contains the offset, in bytes, of the shared memory.

Remarks

An NDIS 6.20 or later driver can use the NET_BUFFER_SHARED_MEM_OFFSET macro to get shared memory offset that is associated with a NET_BUFFER_SHARED_MEMORY structure. NET_BUFFER_SHARED_MEM_OFFSET gets the offset from the SharedMemoryOffset member of the NET_BUFFER_SHARED_MEMORY structure. The SharedMemoryInfo member of the NET_BUFFER structure contains the first NET_BUFFER_SHARED_MEMORY structure in a linked list.

Requirements

   
Minimum supported client Supported in NDIS 6.20 and later.
