UcxEndpointNeedToCancelTransfers function (ucxendpoint.h)

The client driver calls this method before it cancels transfers on the wire.

Syntax

void UcxEndpointNeedToCancelTransfers(
  [in] UCXENDPOINT Endpoint
);

Parameters

[in] Endpoint

A handle to the endpoint object. The client driver retrieved the handle in a previous call to UcxEndpointCreate.

Return value

None

Remarks

If needed, UCX coordinates with the hub driver to send a Clear TT buffer command to the TT Hub.

After that operation completes, UCX invokes the client driver's EVT_UCX_ENDPOINT_OK_TO_CANCEL_TRANSFERS callback function.
