ds_priority_size

This function will return the "size" of the priority queue, ie: the number of items that have been prioritized in it.

Syntax:

ds_priority_size(id);

Returns:

Real

Example:

if !ds_priority_empty(control_priority)
    {
    num = ds_priority_size(control_priority);
    }

The above code checks a DS priority 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.
