...But, to actually link to the function (mult2ints), the EXTERNDEF mult2ints:PROC declaration is not sufficient. One also has to explicitly link to the function in the .dll. And, it appears that the mult2ints symbol in the .dll must be declared PUBLIC in the .dll. It's a nuisance, but it works. Much more efficient to use the mult2ints PROTO declaration.
