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.
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.
DAT_SUCCESS
The operation was successful.
DAT_INVALID_HANDLE
The ep_handle parameter is invalid.
