in reply to Re^3: How do I prototype a function with a varying number of arguments?
in thread How do I prototype a function with a varying number of arguments?

... how is it, that putting a limitation on the number and type of arguments that can be passed to a function, make it generic and more suitable to use as a standby function?

How do you pass the elements of a two-item array to a function with the $$ prototype?
