dat_ep_reset - transition the local Endpoint from a Disconnected to an Unconnected state
SYNOPSIS
cc [ flag... ] file... -ldat [ library... ]
#include <dat/udat.h>
DAT_RETURN
dat_ep_reset (
IN DAT_EP_HANDLE ep_handle
)
PARAMETERS
ep_handle Handle for an instance of Endpoint.
DESCRIPTION
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.
RETURN VALUES
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.
USAGE
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.

dat_ep_get_status(3DAT) Direct Access Transport Library Functions dat_ep_get_status(3DAT)NAME
dat_ep_get_status - provide a quick snapshot of the Endpoint
SYNOPSIS
cc [ flag... ] file... -ldat [ library... ]
#include <dat/udat.h>
DAT_RETURN
dat_ep_get_status (
IN DAT_EP_HANDLE ep_handle,
OUT DAT_EP_STATE *ep_state,
OUT DAT_BOOLEAN *recv_idle,
OUT DAT_BOOLEAN *request_idle
)
PARAMETERS
ep_handle Handle for an instance of the Endpoint.
ep_state Current state of the Endpoint.
recv_idle Status of the incoming DTOs on the Endpoint.
request_idle Status of the outgoing DTOs and RMR Bind operations on the Endpoint.
DESCRIPTION
the dat_ep_get_status() function provides the Consumer a quick snapshot of the Endpoint. The snapshot consists of the Endpoint state and
whether there are outstanding or in-progress, incoming or outgoing DTOs. Incoming DTOs consist of Receives. Outgoing DTOs consist of the
Requests, Send, RDMA Read, RDMA Write, and RMR Bind.
The ep_state parameter returns the value of the current state of the Endpoint ep_handle. State value is one of the following:
DAT_EP_STATE_UNCONNECTED, DAT_EP_STATE_RESERVED, DAT_EP_STATE_PASSIVE_CONNECTION_PENDING, DAT_EP_STATE_ACTIVE_CONNECTION_PENDING,
DAT_EP_STATE_TENTATIVE_CONNECTION_PENDING, DAT_EP_STATE_CONNECTED, DAT_EP_STATE_DISCONNECT_PENDING, or DAT_EP_STATE_DISCONNECTED.
A recv_idle value of DAT_TRUE specifies that there are no outstanding or in-progress Receive DTOs at the Endpoint, and DAT_FALSE otherwise.
A request_idle value of DAT_TRUE specifies that there are no outstanding or in-progress Send, RDMA Read, and RDMA Write DTOs, and RMR Binds
at the Endpoint, and DAT_FALSE otherwise.
This call provides a snapshot of the Endpoint status only. No heroic synchronization with DTO queuing or processing is implied.
RETURN VALUES
DAT_SUCCESS The operation was successful.
DAT_INVALID_HANDLE The ep_handle parameter is invalid.
