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

131 <div id="init_flags_CONTENT">
132 <p>As with the C language API, SDL_perl initializes the SDL environment through
133 the <code>SDL::init</code> subroutine. This routine takes a mode flag constructed through
134 the bitwise OR product of the following constants:</p>
145 INIT_NOPARACHUTE</dt>
151 <p><code>SDL::Init</code> returns 0 on success, or -1 on error.</p>

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

162 <div id="quit_subsystem_flags_CONTENT">
163 <p>SDL::quit_subsystem allows you to shut down a subsystem that has been previously initialized by SDL::init or SDL::init_subsystem.
164 The flags tells SDL::quit_subSystem which subsystems to shut down, it uses the same values that are passed to SDL::init. </p>
165 <p>SDL::quit_subsystem doesn't returns any value.</p>

176 <p>SDL::was_init allows you to see which SDL subsytems have been initialized.
177 flags is a bitwise OR'd combination of the subsystems you wish to check (see SDL::init for a list of subsystem flags).
178 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>

214 Note 1: SDL_LASTERROR marks the highest numbered predefined error.
215 Note 2: SDL also defines SDL_OutOfMemory() and SDL_Unsupported() for internal use
216 which are equivalent to SDL_Error(SDL_ENOMEM) and SDL_Error(SDL_UNSUPPORTED) respectively.
