I want to call std::lower_bound with one of these functions. std::lower_bound accepts a function pointer just fine without any overloading. However, when I add an additional overloaded function, the compiler (g++ 3.2) understandibly gets confused. How do I disambiguate?

With a cast. bool f (int, int); bool f (double, double); lower_bound(v.begin(), v.end(), 42, static_cast<bool (*) (int, int)>(f)); You could also use a pointer variable. bool (*fInt) (int, int) (f); lower_bound(v.begin(), v.end(), 42, fint); John [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.
