An overloaded name (same name used with different argument types)
An ambiguous name (same name used in different classes)
You might want to qualify an overloaded function name. If you do not qualify it, dbx displays an overload list so you can choose which function you will navigate. If you know the function class name, you can use it with the double colon scope resolution operator to qualify the name.
(dbx) func class::function_name (args)
For example, if hand is the class name and draw is the function name, type:
(dbx) func hand::draw
