SDL_WasInit

Description

SDL_WasInit allows you to see which SDL subsytems have been initialized. flags is a bitwise OR'd combination of the subsystems you wish to check (see SDL_Init for a list of subsystem flags).

Return Value

SDL_WasInit returns a bitwised OR'd combination of the initialized subsystems.

Examples

// Here are several ways you can use SDL_WasInit

// Get init data on all the subsystems 
var
  subsystem_init : Uint32;
.
.
.
subsystem_init := SDL_WasInit( SDL_INIT_EVERYTHING );

if ( ( subsystem_init and SDL_INIT_VIDEO ) = true ) then
  Writeln( 'Video is initialized.' )
else
  Writeln( 'Video is not initialized.' );



// Just check for one specfic subsystem

if ( SDL_WasInit( SDL_INIT_VIDEO ) <> 0 ) then
  Writeln( 'Video is initialized. ')
else
  Writeln( 'Video is not initialized.' );




// Check for two subsystems
var
  subsystem_mask : UInt32;
.
.

  subsystem := SDL_INIT_VIDEO or SDL_INIT_AUDIO;

if ( SDL_WasInit( subsystem_mask ) = subsystem_mask ) then
  Writeln( 'Video and Audio initialized.' )
else
  Writeln( 'Video and Audio not initialized.' );
