.\" .AP type name in/out [indent]
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",

.\" .AS [type [name]]
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed

.SH NAME
dp_address \- internet address record manipulation
.BE
.TP
\fBdp_address \fIoption ?arg arg ...?\fR

The dp_address command provides access to an internal array of
internet address records.  These address records are appropriate
for use as arguments to the dp_sendTo and receiveFrom
network communication commands of Tcl-DP (Tcl Distributed
Programming).  The argument \fIoption\fP specifies the operation
to be performed.  The valid options are:
.RS
.TP
\fBdp_address create \fIhost port\fR

Creates an internal address record that represents the given
\fIhost\fR address and \fIport\fR number internet information.
Returns an \fIaddr\fR handle that is appropriate for use as an
argument to the dp_sendTo and dp_receiveFrom commands and
as the \fIaddr\fP argument in the commands below.
.TP
\fBdp_address delete \fIaddr\fR

Delete the previously created internal address record that has
the given \fIaddr\fP handle.
.TP
\fBdp_address info \fIaddr\fR

Return a list of the form \fI{host port}\fP, which is the
internet information stored with the given \fIaddr\fR handle.
