Hi Simms,

my personal opinion regarding coding style is to not use exit in the middle of any program - at least not until the block of code is that short that the exit is not visible immediately - and I almost never use an exit within a function.

If it's just 10 lines coding style may be ignored all the way and I would say: Don't make a mountain out of a molehill.

io::async::loop::glib

IO::Async::Loop::Glib(3pm)				User Contributed Perl Documentation				IO::Async::Loop::Glib(3pm)

NAME

       "IO::Async::Loop::Glib" - use "IO::Async" with Glib or GTK

SYNOPSIS

	use IO::Async::Loop::Glib;

	my $loop = IO::Async::Loop::Glib->new();

	$loop->add( ... );

	...
	# Rest of GLib/Gtk program that uses GLib

	Glib::MainLoop->new->run();

       Or

	$loop->loop_forever();

       Or

	while(1) {
	   $loop->loop_once();
	}

DESCRIPTION

       This subclass of "IO::Async::Loop" uses the "Glib::MainLoop" to perform read-ready and write-ready tests.

       The appropriate "Glib::IO" sources are added or removed from the "Glib::MainLoop" when notifiers are added or removed from the set, or when
       they change their "want_writeready" status. The callbacks are called automatically by Glib itself; no special methods on this loop object
       are required.

CONSTRUCTOR

   $loop = IO::Async::Loop::Glib->new()
       This function returns a new instance of a "IO::Async::Loop::Glib" object. It takes no special arguments.

METHODS

       There are no special methods in this subclass, other than those provided by the "IO::Async::Loop" base class.

   $count = $loop->loop_once( $timeout )
       This method calls the "iteration()" method on the underlying "Glib::MainContext". If a timeout value is supplied, then a Glib timeout will
       be installed, to interrupt the loop at that time. If Glib indicates that any callbacks were fired, then this method will return 1 (however,
       it does not mean that any "IO::Async" callbacks were invoked, as there may be other parts of code sharing the Glib main context. Otherwise,
       it will return 0.

SEE ALSO

       o   Glib - Perl wrappers for the GLib utility and Object libraries

       o   Gtk2 - Perl interface to the 2.x series of the Gimp Toolkit library
