=head1 NAME
X11::Protocol::Ext::XC_MISC - Perl module for the X11 Protocol XC-MISC Extension
=head1 SYNOPSIS
use X11::Protocol;
$x = X11::Protocol->new();
$x->init_extension('XC-MISC');
=head1 DESCRIPTION
This module is used by the programmer to pre-acquire large numbers of
X resource IDs to be used with the X11::Protocol module.
If supported by the server, X11::Protocol will load this module
automatically when additional resource IDs are needed via the standard
new_rsrc() interface. However, if you anticipate that a program will
run for a long time and allocate many resources, it would be a good
idea to initialize the extension at startup to verify its existence.
=head1 REQUESTS
This extension adds three requests, called as shown below:
$x->XCMiscGetVersion => ($major, $minor)
$x->XCMiscGetXIDRange => ($start_id, $count)
$x->XCMiscGetXIDList($count) => ($count, @ids)
