SDL_WasInit(3)
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.
- ");
