ds_queue_size

This function will return the "size" of the queue, ie: the number of items that have been queued onto it.

Syntax:

ds_queue_size(id);

Returns:

Real

Example:

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.
