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

Assign a tag to a channel.

## Syntax

```c
int Mix_GroupChannel(int which, int tag);

```

## Function Parameters

|               |                                         |
| ------------- | --------------------------------------- |
| **which**     | the channel to set the tag on.          |
| **tag**       | an arbitrary value to assign a channel. |

## Return Value

Returns non-zero on success, zero on error (no such channel).

## Remarks

A tag is an arbitary 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 2.0.0.
