(This function is part of SDL_mixer, a separate library from SDL.)

Mix_UnregisterEffect

Explicitly unregister a special effect function.

Header File

Defined in <SDL3_mixer/SDL_mixer.h>

Syntax

bool Mix_UnregisterEffect(int channel, Mix_EffectFunc_t f);

Function Parameters

int	channel	the channel to unregister an effect on, or MIX_CHANNEL_POST.
Mix_EffectFunc_t	f	effect the callback stop calling in future mixing iterations.

Return Value

(bool) Returns true on success or false on failure; call SDL_GetError() for more information.

Remarks

You may not need to call this at all, unless you need to stop an effect from processing in the middle of a chunk's playback.

Posteffects are never implicitly unregistered as they are for channels (as the output stream does not have an end), but they may be explicitly unregistered through this function by specifying MIX_CHANNEL_POST for a channel.

Version

This function is available since SDL_mixer 3.0.0.
