SDL_WasInit- Check which subsystems are initialized
#include "SDL.h"
Uint32 SDL_WasInit(Uint32 flags);
SDL_WasInit allows you to see which SDL subsytems have been initialized. flags is a bitwise ORd combination of the subsystems you wish to check (see SDL_Init for a list of subsystem flags).
SDL_WasInit returns a bitwised ORd combination of the initialized subsystems.
/* 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. ");
