.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`IO::Socket::UNIX\*(C'\fR provides an object interface to creating and using sockets
in the \s-1AF_UNIX\s0 domain. It is built upon the IO::Socket interface and
inherits all the methods defined by IO::Socket.
.SH "CONSTRUCTOR"
.IX Header "CONSTRUCTOR"
.IP "new ( [\s-1ARGS\s0] )" 4
.IX Item "new ( [ARGS] )"
Creates an \f(CW\*(C`IO::Socket::UNIX\*(C'\fR object, which is a reference to a
newly created symbol (see the \f(CW\*(C`Symbol\*(C'\fR package). \f(CW\*(C`new\*(C'\fR
optionally takes arguments, these arguments are in key-value pairs.
.Sp
In addition to the key-value pairs accepted by IO::Socket,
\&\f(CW\*(C`IO::Socket::UNIX\*(C'\fR provides.
.Sp
.Vb 4
\& Type Type of socket (eg SOCK_STREAM or SOCK_DGRAM)
\& Local Path to local fifo
\& Peer Path to peer fifo
\& Listen Queue size for listen
.Ve
.Sp
If the constructor is only passed a single argument, it is assumed to
be a \f(CW\*(C`Peer\*(C'\fR specification.
.Sp
If the \f(CW\*(C`Listen\*(C'\fR argument is given, but false, the queue size will be set to 5.
.Sp
If the constructor fails it will return \f(CW\*(C`undef\*(C'\fR and set the
\&\f(CW$IO::Socket::errstr\fR package variable to contain an error message.
.Sp
.Vb 2
\& $sock = IO::Socket::UNIX\->new(...)
\& or die "Cannot create socket \- $IO::Socket::errstr\en";
.Ve
.Sp
For legacy reasons the error message is also set into the global \f(CW$@\fR
variable, and you may still find older code which looks here instead.
.Sp
.Vb 2
\& $sock = IO::Socket::UNIX\->new(...)
\& or die "Cannot create socket \- $@\en";
.Ve
.SH "METHODS"

Returns the pathname to the fifo at the local end
.IP "\fBpeerpath()\fR" 4

Returns the pathanme to the fifo at the peer end
