Note NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.

NDIS_BUFFER_LINKAGE returns a pointer to a linked buffer, given a pointer to a buffer descriptor.

Syntax

PVOID NDIS_BUFFER_LINKAGE(
  _In_ PNDIS_BUFFER Buffer
);

Buffer [in]
Pointer to a buffer descriptor. This buffer descriptor must not be chained to a packet descriptor.

NDIS_BUFFER_LINKAGE returns a pointer to the structure member containing the linkage, or NULL if it fails.

This macro allows a driver to queue allocated buffer descriptors without having to supply its own buffer descriptor linkage.
