Overview
This module is an abstract base class for the various X11::Protocol::Connection::* modules that provide connections to X servers for the X11::Protocol module. It provides stubs for the following methods:
open
$conn = X11::Protocol::Connection::Foo->open($host, $display_num)Open a connection to the specified display (numbered from 0) on the specified $host.
give
$conn->give($data)Send the given data to the server. Normally, this method is used only by the protocol module itself.
get
$data = $conn->get($n)Read $n bytes of data from the server. Normally, this method is used only by the protocol module itself.
fh
$filehandle = $conn->fhReturn an object suitable for use as a filehandle. This is mainly useful for doing select() and other such system calls.
