19.10.3.3 Optional members [pointer.traits.optmem]

Specializations of pointer_­traits may define the member declared in this subclause to customize the behavior of the standard library.
static element_type* to_address(pointer p) noexcept;
Returns: A pointer of type element_­type* that references the same location as the argument p.
[Note
:
This function should be the inverse of pointer_­to.
If defined, it customizes the behavior of the non-member function to_­address ([pointer.conversion]).
