返回： Real（实数）
This function will return the "size" of the queue, ie: the
number of items that have been queued onto it.
if !ds_queue_empty(control_queue)
{
num = ds_queue_size(control_queue);
}
The above code checks a ds_queue to see if it is empty or not, and if it is not, it gets the number of items that it contains and stores the value in a variable.
