I have some class "foo": class foo {...}; And I have some function bar: void bar(const foo& foo2) { foo2.member(); } This generates a "warning: passing `const foo' as `this' argument of `void foo::member()' discards const". Does this mean that I can't call any member functions of a class which is passed as a const-reference without risking modification of the class data? I could just remove the 'const', but I did it to prevent other warning messages like if I were to call "bar((foo)5)". -- (\/) Endlisnis (\/) s257m AT unb DOT ca Endlisnis AT HotMail DOT com ICQ: 32959047
