Explicitly unregister all special effect functions.
Defined in <SDL3_mixer/SDL_mixer.h>
bool Mix_UnregisterAllEffects(int channel);
int | channel | the channel to unregister all effects on, or MIX_CHANNEL_POST. |
(bool) Returns true on success or false on failure; call SDL_GetError() for more information.
You may not need to call this at all, unless you need to stop all effects from processing in the middle of a chunk's playback.
Note that this will also shut off some internal effect processing, since Mix_SetPanning() and others may use this API under the hood. This is called internally when a channel completes playback. Posteffects are never implicitly unregistered as they are for channels, but they may be explicitly unregistered through this function by specifying MIX_CHANNEL_POST for a channel.
Note that unlike most SDL and SDL_mixer functions, this function returns zero if there's an error, not on success. We apologize for the API design inconsistency here.
This function is available since SDL_mixer 3.0.0.
