# MIX_SetTrackGroup

Assign a track to a mixing group.

## Header File

Defined in [<SDL3_mixer/SDL_mixer.h>](https://github.com/libsdl-org/SDL_mixer/blob/main/include/SDL3_mixer/SDL_mixer.h)

## Syntax

```c
bool MIX_SetTrackGroup(MIX_Track *track, MIX_Group *group);
```

## Function Parameters

|                          |           |                                                 |
| ------------------------ | --------- | ----------------------------------------------- |
| [MIX_Track](MIX_Track) * | **track** | the track to set mixing group assignment.       |
| [MIX_Group](MIX_Group) * | **group** | the new mixing group to assign to. May be NULL. |

## Return Value

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

## Remarks

All tracks in a group are mixed together, and that output is made available
to the app before it is mixed into the final output.

Tracks can only be in one group at a time, and the track and group must
have been created on the same [MIX_Mixer](MIX_Mixer).

Setting a track to a NULL group will remove it from any app-created groups,
and reassign it to the mixer's internal default group.

## Thread Safety

It is safe to call this function from any thread.

## Version

This function is available since SDL_mixer 3.0.0.
