Function Documentation

audio_sdl_init()

void audio_sdl_init

(

void

)

Initialize. Note that this function is called very early at the client startup. So for example logging isn't available.

init_sdl_audio()

static bool init_sdl_audio ( void  )

static

Init SDL. If the video is already in use (by gui-sdl2), just init the subsystem.

This will need to be changed if SDL is used elsewhere.

quit_sdl_audio()

static void quit_sdl_audio ( void  )

static

Quit SDL. If the video is still in use (by gui-sdl2), just quit the subsystem.

This will need to be changed if SDL is used elsewhere.
