NAME

       ModPerl::Global -- Perl API for manipulating special Perl lists

Synopsis
	 use ModPerl::Global ();
	 my $package = 'MyApache2::Package';

	 # make the END blocks of this package special
	 ModPerl::Global::special_list_register(END => $package);

	 # Execute all encoutered END blocks from this package now
	 ModPerl::Global::special_list_call(	END => $package);

	 # delete the list of END blocks
	 ModPerl::Global::special_list_clear(	END => $package);

Description
       "ModPerl::Global" provides an API to manipulate special perl lists. At the moment only the "END" blocks list is supported.

       This API allows you to change the normal Perl behavior, and execute special lists when you need to.

       For example "ModPerl::RegistryCooker" uses it to run "END" blocks in the scripts at the end of each request.

       Before loading a module containing package $package, you need to register it, so the special blocks will be intercepted by mod_perl and not
       given to Perl. "special_list_register" does that. Later on when you want to execute the special blocks, "special_list_call" should be
       called. Unless you want to call the list more than once, clear the list with "special_list_clear".

API

       "ModPerl::Global" provides the following methods:

   "special_list_call"
       Call the special list

	 $ok = special_list_call($key => $package);

       arg1: $key ( string )
	   The name of the special list. At the moment only 'END' is supported.

       arg2: $package ( string )
	   what package to special list is for

       ret: $ok ( boolean )
	   true value if $key is known, false otherwise.

       since: 2.0.00

   "special_list_clear"
       Clear the special list

	 $ok = special_list_clear($key => $package);

       arg1: $key ( string )
	   The name of the special list. At the moment only 'END' is supported.

       arg2: $package ( string )
	   what package to special list is for

       ret: $ok ( boolean )
	   true value if $key is known, false otherwise.

       since: 2.0.00

   "special_list_register"
       Register the special list

	 $ok = special_list_call($key => $package);

       arg1: $key ( string )
	   The name of the special list. At the moment only 'END' is supported.

       arg2: $package ( string )
	   what package to special list is for

       ret: $ok ( boolean )
	   true value if $key is known, false otherwise.

       since: 2.0.00

       Notice that you need to register the package before it is loaded. If you register it after, Perl has already compiled the "END" blocks and
       there are no longer under your control.
