Halt playing of a group of channels by arbitrary tag.
int Mix_HaltGroup(int tag);
|tag||an arbitrary value, assigned to channels, to search for.|
Returns zero, whether any channels were halted or not.
This will stop further playback on all channels with a specific tag, until a new chunk is started there.
A tag is an arbitary number that can be assigned to several mixer channels, to form groups of channels.
The default tag for a channel is -1.
Any halted channels will have any currently-registered effects deregistered, and will call any callback specified by Mix_ChannelFinished() before this function returns.
This function is available since SDL_mixer 2.0.0.
