###### (This function is part of SDL_mixer, a separate library from SDL.) # Mix_EffectDone_t This is a callback that signifies that a channel has finished all its loops and has completed playback. ## Header File Defined in [](https://github.com/libsdl-org/SDL_mixer/blob/SDL2/include/SDL_mixer.h) ## Syntax ```c typedef void (SDLCALL *Mix_EffectDone_t)(int chan, void *udata); ``` ## Remarks This gets called if the buffer plays out normally, or if you call [Mix_HaltChannel](Mix_HaltChannel)(), implicitly stop a channel via [Mix_AllocateChannels](Mix_AllocateChannels)(), or unregister a callback while it's still playing. DO NOT EVER call SDL_LockAudio() from your callback function! ---- [CategoryAPI](CategoryAPI), [CategoryAPIDatatype](CategoryAPIDatatype)
