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 subsys-
     tems.

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.
     ");
