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


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


int Mix_UnregisterAllEffects(int channel);

Function Parameters



Return Value

Returns zero if error (no such channel), nonzero if all effects removed. Error messages can be retrieved from Mix_GetError().


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.


This function is available since SDL_mixer 2.0.0.
