Windows Driver Kit DDI reference (nc-ucxendpoint-evt_ucx_endpoint_get_isoch_transfer_path_delays)

EVT_UCX_ENDPOINT_GET_ISOCH_TRANSFER_PATH_DELAYS callback function

Description

UCX invokes this callback function to get information about transfer path delays for an isochronous endpoint.

Parameters

UcxEndpoint [in]

A handle to a UCXENDPOINT object that represents the isochronous endpoint for which the client driver receives the transfer path delays.

UcxEndpointTransferPathDelays [in, out]

A pointer to a UCX_ENDPOINT_ISOCH_TRANSFER_PATH_DELAYS structure that contains transfer path delay values.

Return value

If the operation is successful, the callback function must return STATUS_SUCCESS, or another status value for which NT_SUCCESS(status) equals TRUE. Otherwise it must return a status value for which NT_SUCCESS(status) equals FALSE.

Remarks

The UCX client driver registers this callback function with the USB host controller extension (UCX) by calling the UcxEndpointCreate method.
