.SH DESCRIPTION
.sp
.LP
The \fBdat_ep_query()\fR function provides the Consumer parameters, including
attributes and status, of the Endpoint. Consumers pass in a pointer to
Consumer-allocated structures for Endpoint parameters that the Provider fills.
.sp
.LP
The \fIep_param_mask\fR parameter allows Consumers to specify which parameters
to query. The Provider returns values for \fIep_param_mask\fR requested
parameters. The Provider can return values for any other parameters.
.sp
.LP
Some of the parameters only have values for certain Endpoint states.
Specifically, the values for \fIremote_ia_address\fR and \fIremote_port_qual\fR
are valid only for Endpoints in the
\fBDAT_EP_STATE_PASSIVE_CONNECTION_PENDING\fR,
\fBDAT_EP_STATE_ACTIVE_CONNECTION_PENDING\fR,
\fBDAT_EP_STATE_TENTATIVE_CONNECTION_PENDING\fR,
\fBDAT_EP_STATE_DISCONNECT_PENDING\fR, \fBDAT_EP_STATE_COMPLETION_PENDING\fR,
or \fBDAT_EP_STATE_CONNECTED\fR states. The values of \fIlocal_port_qual\fR is
valid only for Endpoints in the \fBDAT_EP_STATE_PASSIVE_CONNECTION_PENDING\fR,
\fBDAT_EP_STATE_ACTIVE_CONNECTION_PENDING\fR,
\fBDAT_EP_STATE_DISCONNECT_PENDING\fR, \fBDAT_EP_STATE_COMPLETION_PENDING\fR,
or \fBDAT_EP_STATE_CONNECTED\fR states, and might be valid for
\fBDAT_EP_STATE_UNCONNECTED\fR, \fBDAT_EP_STATE_RESERVED\fR,
\fBDAT_EP_STATE_TENTATIVE_CONNECTION_PENDING\fR,
\fBDAT_EP_STATE_PASSIVE_CONNECTION_PENDING\fR, and
\fBDAT_EP_STATE_UNCONNECTED\fR states.
