EVT_UCX_ENDPOINT_GET_ISOCH_TRANSFER_PATH_DELAYS callback function (ucxendpoint.h)

  • Artikel

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

Syntax

EVT_UCX_ENDPOINT_GET_ISOCH_TRANSFER_PATH_DELAYS EvtUcxEndpointGetIsochTransferPathDelays;

NTSTATUS EvtUcxEndpointGetIsochTransferPathDelays(
  [in]      UCXENDPOINT UcxEndpoint,
  [in, out] PUCX_ENDPOINT_ISOCH_TRANSFER_PATH_DELAYS UcxEndpointTransferPathDelays
)
{...}

Parameters

[in] UcxEndpoint

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

[in, out] UcxEndpointTransferPathDelays

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.
