On the lhs you have declared rf to be a reference to a function.. and on the rhs f is a pointer to a function... Would you expect: int i; int & ri = &i; to compile? In simple terms IMO I do not think there is any syntactic way that you can write a reference to a function (*f does not work because under the rules that is converted to a pointer) Francis Glassborow Chair of Association of C & C++ Users 64 Southfield Rd Oxford OX4 1PA +44(0)1865 246490 All opinions are mine and do not represent those of any organisation [ comp.std.c++ is moderated.
