The KsStreamPointerDelete function deletes a clone stream pointer, releasing a reference on the frame to which this stream pointer referred.

Syntax

void KsStreamPointerDelete(
  [in] PKSSTREAM_POINTER StreamPointer
);

Parameters

[in] StreamPointer

A pointer to a KSSTREAM_POINTER structure representing the clone stream pointer to delete. Must be a clone stream pointer; cannot be the leading or trailing edge stream pointer.

Return value

None

Remarks

If the frame to which StreamPointer points has no other references on it after deletion, it is completed. When the last frame in a given IRP is completed, the IRP is completed.

The leading edge and trailing edge stream pointers for a given queue and pin are special stream pointers that cannot be deleted.
