use SDL;
use SDL ':all';
or access them directly:
SDL::SDL_INIT_AUDIO;
or by choosing the export tags below:
Export tag: ':init'
SDL_INIT_AUDIO SDL_INIT_VIDEO SDL_INIT_CDROM SDL_INIT_EVERYTHING SDL_INIT_NOPARACHUTE SDL_INIT_JOYSTICK SDL_INIT_TIMER
SDL::init( $flags );
As with the C language API, SDL Perl initializes the SDL environment with the "SDL::init" subroutine. This routine takes a mode flag constructed through the bitwise OR product of the "SDL_INIT_*" constants. The $flags tell "SDL::init" which subsystems to initialize.
SDL::init(SDL_INIT_AUDIO | SDL_INIT_JOYSTICK);
"SDL::init" returns 0 on success, or "-1" on error.
SDL::init_sub_system( $flags );
After SDL has been initialized with "SDL::init" you may initialize any uninitialized subsystems with "SDL::init_sub_system". The $flags tell "SDL::init_sub_system" which subsystems to initialize, and are taken in the same way as "SDL::init".
"SDL::init_sub_system" returns 0 on success, or "-1" on error.
SDL::quit_sub_system( $flags );
"SDL::quit_sub_system" allows you to shut down a subsystem that has been previously initialized by "SDL::init" or "SDL::init_sub_system". The $flags tell "SDL::quit_sub_system" which subsystems to shut down, and are taken in the same way as "SDL::init".
"SDL::quit_sub_system" doesn't return any values.
SDL::quit;
"SDL::quit" Shuts down all SDL subsystems, unloads the dynamically linked library and frees the allocated resources.
Note: This will be called automatically when Perl exits. You don't need to call this, except if you want to initialize SDL again after this.
"SDL::quit" doesn't return any values.
my $flags = SDL::was_init( $flags );
"SDL::was_init" allows you to see which SDL subsystems have been initialized. The $flags tell "SDL::was_init" which subsystems to check, and are taken in the same way as "SDL::init".
"SDL::was_init" returns a mask of the initialized subsystems it checks. If $flags is 0 or "SDL_INIT_EVERYTHING", a mask of all initialized subsystems will be returned (this does not include "SDL_INIT_EVENTTHREAD" or "SDL_INIT_NOPARACHUTE").
use SDL ':all';
my $mask = SDL::was_init(SDL_INIT_AUDIO | SDL_INIT_JOYSTICK);
if($mask & SDL_INIT_AUDIO and $mask & SDL_INIT_JOYSTICK) {
# Both subsystems are initialized!
}
my $error = SDL::get_error;
Returns a scalar value containing the last error message set by the SDL library (if any).
SDL::set_error_real( $printf_format, @values )
"SDL::set_error_real" sets the SDL error to a "printf" style formatted string.
"SDL::set_error_real" doesn't return any values.
SDL::clear_error;
"SDL::clear_error" deletes all information about the last SDL error. This is useful if the error has been handled by the program.
"SDL::clear_error" doesn't return any values.
my $version = SDL::version;
Returns an "SDL::Version" object of the SDL library at compile-time.
use SDL;
use SDL::Version;
my $v = SDL::version;
printf("got version: %d.%d.%d\n", $v->major, $v->minor, $v->patch);
my $ticks = SDL::get_ticks;
Returns the number of milliseconds since SDL library initialization. This value wraps around if the program runs for more than 49.7 days
my $win32_handle = SDL::get_handle;
A video surface must be inited to get a handle.
SDL::delay( $ms );
"SDL::delay" waits the specified number of milliseconds before returning. The actual delay may be longer than specified depending on the underlying OS.
"SDL::delay" doesn't return anything.
# Delay for half a second SDL::delay(500);
