=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)
