  _In_       HINTERACTIONCONTEXT interactionContext,
  _In_       UINT32              entriesCount,
  _In_       UINT32              pointerCount,
  _In_ const POINTER_INFO        *pointerInfo
);

Return value

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

Output notifications are sent as required.

Frames must be processed in reverse chronological order (most recent data first).

Each frame must have the same set of input pointers.

Each pointer must originate from a different contact.
