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


Assign several consecutive channels to the same tag.

Header File

Defined in <SDL3_mixer/SDL_mixer.h>


int Mix_GroupChannels(int from, int to, int tag);

Function Parameters

int from the first channel to set the tag on.
int to the last channel to set the tag on, inclusive.
int tag an arbitrary value to assign a channel.

Return Value

(int) Returns 0 if successful, negative on error.


A tag is an arbitrary number that can be assigned to several mixer channels, to form groups of channels.

If 'tag' is -1, the tag is removed (actually -1 is the tag used to represent the group of all the channels).

This function replaces the requested channels' current tags; you may only have one tag per channel.

You may not specify MAX_CHANNEL_POST for a channel.

Note that this returns success and failure in the opposite way from Mix_GroupChannel(). We regret the API design mistake.


This function is available since SDL_mixer 3.0.0.
