###### (This function is part of SDL_mixer, a separate library from SDL.) # Mix_GroupChannel Assign a tag to a channel. ## Header File Defined in [](https://github.com/libsdl-org/SDL_mixer/blob/main/include/SDL3_mixer/SDL_mixer.h) ## Syntax ```c bool Mix_GroupChannel(int which, int tag); ``` ## Function Parameters | | | | | --- | --------- | --------------------------------------- | | int | **which** | the channel to set the tag on. | | int | **tag** | an arbitrary value to assign a channel. | ## Return Value (bool) Returns true on success or false on failure; call SDL_GetError() for more information. ## Remarks 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 channel's current tag; you may only have one tag per channel. You may not specify MAX_CHANNEL_POST for a channel. ## Version This function is available since SDL_mixer 3.0.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction)
