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.
");
