dat_ep_reset - transition the local Endpoint from a Disconnected to an Unconnected state
cc [ flag... ] file... -ldat [ library... ] #include <dat/udat.h> DAT_RETURN dat_ep_reset ( IN DAT_EP_HANDLE ep_handle )
ep_handle Handle for an instance of Endpoint.
The dat_ep_reset() function transitions the local Endpoint from a Disconnected 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 Unconnected 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.
DAT_SUCCESS The operation was successful. DAT_INVALID_HANDLE ep_handle is invalid. DAT_INVALID_STATE 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 guar- anteed that all previously posted DTO and RMR completions for the Endpoint were dequeued for that EVD. Now, it is safe to reset the End- point without losing any completions.
