Two functions (members or not) which have the same name but different argument types are completely separate functions. The fact that they have the same name is (almost[1]) entirely cosmetic; you could just as easily give them separate names. E.g. if you have: void foo(int); void foo(float); you could equally just use: void foo_i(int); void foo_f(float); Overloading just lets you omit the type annotation from the name. [1] The only situation where the ability to overload function names really makes a difference is when using templates. -- Glynn Clements <glynn@xxxxxxxxxxxxxxxxxx> - : send the line "unsubscribe linux-c-programming" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
