.SH DESCRIPTION
.sp
.LP
The \fBdat_cr_query()\fR function provides to the Consumer parameters of the
Connection Request. The Consumer passes in a pointer to the Consumer-allocated
structures for Connection Request parameters that the Provider fills.
.sp
.LP
The \fIcr_param_mask\fR parameter allows Consumers to specify which parameters
to query. The Provider returns values for \fIcr_param_mask\fR requested
parameters. The Provider can return values for any other parameters.
.SH RETURN VALUES

.SH USAGE
.sp
.LP
The Consumer uses \fBdat_cr_query()\fR to get information about requesting a
remote Endpoint as well as a local Endpoint if it was allocated by the Provider
for the arrived Connection Request. The local Endpoint is created if the
Consumer used PSP with \fBDAT_PSP_PROVIDER\fR as the value for \fIpsp_flags\fR.
For the remote Endpoint, \fBdat_cr_query()\fR provides \fIremote_ia_address\fR
and \fIremote_port_qual\fR. It also provides remote \fIpeer private_data\fR and
its size.
