Change the expiration delay for a particular channel.
int Mix_ExpireChannel(int channel, int ticks);
|channel||the channel to change the expiration time on.|
|ticks||number of milliseconds from now to let channel play before halting, -1 to not halt.|
Returns the number of channels that changed expirations.
The channel will halt after the 'ticks' milliseconds have elapsed, or remove the expiration if 'ticks' is -1.
This overrides the value passed to the fourth parameter of Mix_PlayChannelTimed().
Specifying a channel of -1 will set an expiration for all channels.
Any halted channels will have any currently-registered effects deregistered, and will call any callback specified by Mix_ChannelFinished() once the halt occurs.
Note that this function does not block for the number of ticks requested; it just schedules the chunk to expire and notes the time for the mixer to manage later, and returns immediately.
This function is available since SDL_mixer 2.0.0.
