NAME

       SDL::Time - An SDL Perl extension for managing timers

CATEGORY

       Core

SYNOPSIS

	use warnings;
	use strict;

	use threads;
	use threads::shared;

	use SDL::Time;

	package foo;

	use SDL ':all';

	SDL::init(SDL_INIT_TIMER);

	my $tick :shared = 0;
	sub ticker { $tick++; warn $tick; return 100; }

	package main;

	my $id = SDL::Time::add_timer(100, 'foo::ticker');

	sleep(2);

	SDL::Time::remove_timer($id);

METHODS

   add_timer
	my $id = SDL::Timer::add_timer( $ms_interval, $callback );

       This runs in a separate thread and a cloned Perl thread.  "threads" and "threads::shared" must be used to share any variables the timer
       uses.

       The $callback function, specified with a string of the function's name, will be called after the milliseconds of $interval have elapsed.
       The actual delay may be longer than specified depending on the underlying OS.  The callback function is passed the current timer interval
       as well as the $interval parameter and should return the next timer interval.  If the return value from the callback is 0, the timer is
       cancelled; otherwise, the timer will continue to run.

       The timer callback function may run in a different thread to your main program, so it shouldn't call any functions from within itself.  You
       may call SDL::push_event, however.

       "SDL::Time::add_timer" returns the identifier value of the generated timer or undef on error.

       Note: You must initialize ("SDL::init") the timer subsystem to use this function.

   remove_timer
	SDL::Timer::remove_timer( $id );

       The other way to cancel a timer is to use "SDL::Time::remove_timer" on the $id of a timer.  This ID is the return value of the
       "SDL::Time::add_timer" function.

       "SDL::Time::remove_timer" returns 0 on success or "-1" on error.
