57 <p>SDL_perl is a package of perl modules that provides both functional and object orient
58 interfaces to the Simple DirectMedia Layer for Perl 5. This package does take some
59 liberties with the SDL API, and attempts to adhere to the spirit of both the SDL
60 and Perl. This document describes the low-level functional SDL_perl API. For the
61 object oriented programming interface please see the documentation provided on a

133 <p>As with the C language API, SDL_perl initializes the SDL environment through
134 the <code>SDL::init</code> subroutine. This routine takes a mode flag constructed through
135 the bitwise OR product of the following constants:</p>
146 INIT_NOPARACHUTE</dt>
152 <p><code>SDL::Init</code> returns 0 on success, or -1 on error.</p>

156 <div id="init_subsystem_flags_CONTENT">
157 <p>After SDL has been initialized with SDL::init you may initialize uninitialized subsystems with SDL::init_subsystem.
158 The flags parameter is the same as that used in SDL::init. </p>
159 <p>SDL::init_subsystem returns 0 on success, or -1 on error.</p>

163 <div id="quit_subsystem_flags_CONTENT">
164 <p>SDL::quit_subsystem allows you to shut down a subsystem that has been previously initialized by SDL::init or SDL::init_subsystem.
165 The flags tells SDL::quit_subSystem which subsystems to shut down, it uses the same values that are passed to SDL::init. </p>

177 <p>SDL::was_init allows you to see which SDL subsytems have been initialized.
178 flags is a bitwise OR'd combination of the subsystems you wish to check (see SDL::init for a list of subsystem flags).
179 If 'flags' is 0 or SDL_INIT_EVERYTHING, it returns a mask of all initialized subsystems (this does not include SDL_INIT_EVENTTHREAD or SDL_INIT_NOPARACHUTE).</p>
