Cheers!!

Speaking of classes, and this may have been answered elsewhere, 
but I am yet to find said answer, or am just missing something 
right in front of my face...but how does one go about accessing a 
method from a class if said class is passed to a function as a 
pointer?  By that I mean something like

class Foo {
     void fooMethod() {

}

void bar(Foo *f) {

}
