EVT_UCX_CONTROLLER_GET_FRAME_NUMBER_AND_QPC_FOR_TIME_SYNC callback function

Description

UCX invokes this callback to retrieves the system query performance counter (QPC) value synchronized with the frame and microframe.

Parameters

UcxController [in]

A handle to the UCX controller that the client driver received in a previous call to the UcxControllerCreate method.

WdfRequest [in]

A framework request object that contains the request to get the synchronized frame and microframe number.

OutputBufferLength [in]
