I'm writing a handle for a  class. How can I overload * and -> operator?

I can't find one on Google

[SiCrane]

struct FooPtr {
  Foo * data;

  Foo & operator*() { return *data; }
  Foo * operator->() { return data; }
};

You overload them exactly the same way you would overload any other operator.  

 

A caveat with A::operator->() must be a nonstatic member function.  (This also applies to =, [], and () operators.)

 

The others can be either a nonstatic member function, or they can be a nonmember function with at least one parameter referencing the class.

Why are you overloading them? If its not similar to what SiCrane has in his example you probably want named functions instead..
