Windows Driver Kit DDI reference (ns-ks-ksbuffer_item)

KSBUFFER_ITEM structure

Description

The KSBUFFER_ITEM structure is used to store a list of data buffers copied from the event source, which can be retrieved by the event sink through KSEVENT_TYPE_QUERYBUFFER.

Members

`DpcItem`

A structure of type KSDPC_ITEM. May be used by internal DPCs; do not use for data buffering.

`BufferList`

Specifies the head of a list of pool allocated buffers that are created by calls to KsGenerateDataEvent for events that have buffering enabled.

Remarks

KSBUFFER_ITEM extends the normal deferred procedure call (DPC) structure, which may be needed for event generation, but does not use the structure itself.
