\&\f(CW\*(C`APR::SockAddr\*(C'\fR provides an access to a socket address structure
fields.
.PP
Normally you'd get a socket address object, by calling:
.PP
.Vb 3
\&  use Apache2::Connection ();
\&  my $remote_sock_addr = $c\->remote_addr;
\&  my $local_sock_addr  = $c\->remote_local;
.Ve
.SH "API"
.IX Header "API"
\&\f(CW\*(C`APR::SockAddr\*(C'\fR provides the following functions and/or methods:
.ie n .Sh """ip_get"""
.el .Sh "\f(CWip_get\fP"
.IX Subsection "ip_get"
Get the \s-1IP\s0 address of the socket
.PP
.Vb 1
\&  $ip = $sock_addr\->ip_get();
.Ve
.ie n .IP "obj: $sock_addr\fR ( \f(CW""APR::SockAddr object"" )" 4

.IX Item "since: 2.0.00"
.PD
.PP
If you are familiar with how perl's \f(CW\*(C`Socket\*(C'\fR works:
.PP
.Vb 3
\&  use Socket \*(Aqsockaddr_in\*(Aq;
\&  my ($serverport, $serverip) = sockaddr_in(getpeername($local_sock));
\&  my ($remoteport, $remoteip) = sockaddr_in(getpeername($remote_sock));

in apr-speak that'd be written as:
.PP

\&  use APR::SockAddr ();
\&  use Apache2::Connection ();
\&  my $serverport = $c\->local_addr\->port;
\&  my $serverip   = $c\->local_addr\->ip_get;
\&  my $remoteport = $c\->remote_addr\->port;
\&  my $remoteip   = $c\->remote_addr\->ip_get;
.Ve
.ie n .Sh """port"""
.el .Sh "\f(CWport\fP"
.IX Subsection "port"
Get the \s-1IP\s0 address of the socket
.PP
.Vb 1
\&  $port = $sock_addr\->port();
.Ve
.ie n .IP "obj: $sock_addr\fR ( \f(CW""APR::SockAddr object"" )" 4

Example: see \f(CW\*(C`ip_get()\*(C'\fR
.SH "Unsupported API"
.IX Header "Unsupported API"
\&\f(CW\*(C`APR::SockAddr\*(C'\fR also provides auto-generated Perl interface for a few
other methods which aren't tested at the moment and therefore their
\&\s-1API\s0 is a subject to change. These methods will be finalized later as a
need arises. If you want to rely on any of the following methods
please contact the the mod_perl development mailing
list so we can help each other take the steps necessary
to shift the method to an officially supported \s-1API\s0.
.ie n .Sh """equal"""
.el .Sh "\f(CWequal\fP"
.IX Subsection "equal"
\&\s-1META:\s0 Autogenerated \- needs to be reviewed/completed
.PP
See if the \s-1IP\s0 addresses in two \s-1APR\s0 socket addresses are
equivalent.  Appropriate logic is present for comparing
IPv4\-mapped IPv6 addresses with IPv4 addresses.
.PP
.Vb 1
\&  $ret = $addr1\->equal($addr2);
.Ve
.ie n .IP "obj: $addr1\fR ( \f(CW""APR::SockAddr object"" )" 4
.el .IP "obj: \f(CW$addr1\fR ( \f(CWAPR::SockAddr object\fR )" 4
.IX Item "obj: $addr1 ( APR::SockAddr object )"
One of the \s-1APR\s0 socket addresses.
.ie n .IP "arg1: $addr2\fR ( \f(CW""APR::SockAddr object"" )" 4
.el .IP "arg1: \f(CW$addr2\fR ( \f(CWAPR::SockAddr object\fR )" 4
.IX Item "arg1: $addr2 ( APR::SockAddr object )"
The other \s-1APR\s0 socket address.
.ie n .IP "ret: $ret ( integer )" 4
.el .IP "ret: \f(CW$ret\fR ( integer )" 4
.IX Item "ret: $ret ( integer )"

The return value will be non-zero if the addresses
are equivalent.
