IN DAT_EP_HANDLE ep_handle
Handle for an instance of Endpoint.
The dat_ep_reset() function transitions the local Endpoint from a Dis‐
connected to an Unconnected state.
The operation might cause the loss of any completions of previously
posted DTOs and RMRs that were not dequeued yet.
The dat_ep_reset() function is valid for both Disconnected and Uncon‐
nected states. For Unconnected state, the operation is no-op because
the Endpoint is already in an Unconnected state. For an Unconnected
state, the preposted Recvs are not affected by the call.
The operation was successful.
ep_handle is invalid.
Parameter in an invalid state. Endpoint is not in
the valid state for reset.
If the Consumer wants to ensure that all Completions are dequeued, the
Consumer can post DTO or RMR operations as a "marker" that are flushed
to recv_evd_handle or request_evd_handle. Now, when the Consumer
dequeues the completion of the "marker" from the EVD, it is guaranteed
that all previously posted DTO and RMR completions for the Endpoint
were dequeued for that EVD. Now, it is safe to reset the Endpoint
without losing any completions.
