Assign a tag to a channel.
int Mix_GroupChannel(int which, int tag);
|which||the channel to set the tag on.|
|tag||an arbitrary value to assign a channel.|
Returns non-zero on success, zero on error (no such channel).
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.
This function is available since SDL_mixer 2.0.0.
