I want to make an method which takes an CGFloat by reference.

Could I do something like this?

- (void)doStuff:(CGFloat*)floatPointer

I guess this must look different than other object pointers which have two of those stars. Also I'm not sure if I must do something like:

- (void)doStuff:(const CGFloat*)floatPointer

And of course, no idea how to assign an CGFloat value to that floatPointer. Maybe &floatPointer = 5.0f; ?

Could someone give some examples and explain these? Would be great!
