NET_BUFFER_SHARED_MEM_HANDLE macro

Description

The NET_BUFFER_SHARED_MEM_HANDLE macro gets the shared memory handle from a NET_BUFFER_SHARED_MEMORY structure.

Syntax

#define NET_BUFFER_SHARED_MEM_HANDLE(_SHI) ((_SHI)->SharedMemoryHandle)

Parameters

_SHI

A pointer to a NET_BUFFER_SHARED_MEMORY structure.

Return value

NET_BUFFER_SHARED_MEM_HANDLE returns an NDIS shared memory handle.

Remarks

An NDIS 6.20 or later driver can use the NET_BUFFER_SHARED_MEM_HANDLE macro to get the shared memory handle that is associated with a NET_BUFFER_SHARED_MEMORY structure. NET_BUFFER_SHARED_MEM_HANDLE gets the handle from the SharedMemoryHandle 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.
