How to get a pointer from a reference?

Question

There seems to be many relavent questions talking about pointer vs. reference, but I couldn\'t find what I want to know. Basically, an object is passed in by a reference:

Answer 1

Use the address-of (&) operator on the reference.

&objRef

Like any other operator used on a reference, this actually affects the referred-to object.

As @Kerrek points out, since the operator affects the referred-to object, if that object has an overloaded operator& function, this will call it instead and std::address_of is needed to get the true address.
