SDL_Init or SDL_InitSubSystem

SDL Development
1

Hi

I have some problem with sdl sound plugin in freeciv.
This pugin can work with others clients ( than SDLClient ) and can be
hotswap or reload during game.

Must I use SDL_Init(SDL_INIT_AUDIO) funt. or I can run only
SDL_InitSubSystem(SDL_INIT_AUDIO)) ( without run SDL_Init(…) ) ?

The same question to SDL_Quit() and SDL_QuitSubSystem(…);

exp.
gtk client with sdl sound plugin.

Run Client.
Start SDL sound plugin ( run only SDL_InitSubSystem(SDL_INIT_AUDIO)) -
init sdl)
start game…
Stop SDL sound plugin ( run only SDL_QuitSubSystem(SDL_INIT_AUDIO)) -
quit sdl)
Start other sound plugin…
…

Yes, this should be fine on UNIX. Windows has dependencies between the
window and the sound device, but that’s not the case on other platforms.

But it is save when I use such sdl init ( and quit ) method with win32
client ( WinAPI ) ?

It should work. You might have to call the internal SDL function
DX5_SoundFocus() with the window handle before initializing audio.
