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.
