.SH DESCRIPTION
.sp
.LP
The \fBdat_ep_reset()\fR function transitions the local Endpoint from a
Disconnected to an Unconnected state.
.sp
.LP
The operation might cause the loss of any completions of previously posted DTOs
and RMRs that were not dequeued yet.
.sp
.LP
The \fBdat_ep_reset()\fR 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.

\fB\fBDAT_SUCCESS\fR\fR

.RS 22n
The operation was successful.

\fB\fBDAT_INVALID_STATE\fR\fR

.RS 22n
Parameter in an invalid state. Endpoint is not in the valid state for reset.

.SH USAGE
.sp
.LP
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
\fIrecv_evd_handle\fR or \fIrequest_evd_handle\fR. Now, when the Consumer
dequeues the completion of the "marker" from the EVD, it is guaranteed that all
previously posted DTO and RMR completions for the Endpoint were dequeued for
that EVD. Now,  it is safe to reset the Endpoint without losing any
completions.
