DESCRIPTION

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->fh

Return an object suitable for use as a filehandle. This is mainly useful for doing select() and other such system calls.
