DESCRIPTION

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.

CONSTRUCTOR

  • 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.

    1

    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

    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.

METHODS

  • hostpath()

    Returns the pathname to the fifo at the local end

  • peerpath()

    Returns the pathanme to the fifo at the peer end
