IO::Socket::UNIX − Object interface for AF_UNIX domain sockets
use

my $server = IO::Socket::UNIX−>new(

"IO::Socket::UNIX" provides an object interface to creating and using sockets in the AF_UNIX domain. It is built upon the IO::Socket interface and inherits all the methods defined by IO::Socket.
new ( [ ARGS ] )
Creates an "IO::Socket::UNIX" object, which is a reference to a newly created symbol (see the "Symbol" package). "new" optionally takes arguments, these arguments are in key-value pairs.
In addition to the key-value pairs accepted by IO::Socket, "IO::Socket::UNIX" provides.
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
If the constructor is only passed a single argument, it is assumed to be a "Peer" specification.
If the "Listen" argument is given, but false, the queue size will be set to 5.
hostpath()
Returns the pathname to the fifo at the local end
peerpath()
Returns the pathanme to the fifo at the peer end
Socket, IO::Socket
