.SH DESCRIPTION
.sp
.LP
the \fBdat_ep_get_status()\fR 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.
.sp
.LP
The \fIep_state\fR parameter returns the value of the current state of the Endpoint \fIep_handle\fR. State value is one of the following: \fBDAT_EP_STATE_UNCONNECTED\fR, \fBDAT_EP_STATE_RESERVED\fR, \fBDAT_EP_STATE_PASSIVE_CONNECTION_PENDING\fR, \fBDAT_EP_STATE_ACTIVE_CONNECTION_PENDING\fR, \fBDAT_EP_STATE_TENTATIVE_CONNECTION_PENDING\fR, \fBDAT_EP_STATE_CONNECTED\fR, \fBDAT_EP_STATE_DISCONNECT_PENDING\fR, or \fBDAT_EP_STATE_DISCONNECTED\fR.
.sp
.LP
A \fIrecv_idle\fR value of \fBDAT_TRUE\fR specifies that there are no outstanding or in-progress Receive DTOs at the Endpoint, and \fBDAT_FALSE\fR otherwise.
.sp
.LP
A \fIrequest_idle\fR value of \fBDAT_TRUE\fR specifies that there are no outstanding or in-progress Send, RDMA Read, and RDMA Write DTOs, and RMR Binds at the Endpoint, and \fBDAT_FALSE\fR otherwise.
.sp
.LP
This call provides a snapshot of the Endpoint status only. No heroic synchronization with DTO queuing or processing is implied.
