Assign a tag to a channel.
Defined in SDL_mixer.h
| 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 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.
This function is available since SDL_mixer 3.0.0.
