.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.
