SDL_WasInit

NAME

SDL_WasInit- Check which subsystems are initialized

SYNOPSIS

#include "SDL.h"

Uint32 SDL_WasInit(Uint32 flags);

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 */

Uint32 subsystem_init;



subsystem_init=SDL_WasInit(SDL_INIT_EVERYTHING);



if(subsystem_init&SDL_INIT_VIDEO)

  printf("Video is initialized.

");

else

  printf("Video is not initialized.

");







/* Just check for one specfic subsystem */



if(SDL_WasInit(SDL_INIT_VIDEO)!=0)

  printf("Video is initialized.

");

else

  printf("Video is not initialized.

");









/* Check for two subsystems */



Uint32 subsystem_mask=SDL_INIT_VIDEO|SDL_INIT_AUDIO;



if(SDL_WasInit(subsystem_mask)==subsystem_mask)

  printf("Video and Audio initialized.

");

else

  printf("Video and Audio not initialized.

");
