std::pointer_traits

Member functions

pointer_traits::pointer_to

 

Defined in header <memory>
static element_type* to_address(pointer p) noexcept;	(1)	(since C++20) (optional member of user-defined specialization)

Constructs a raw pointer that references the same object as its pointer-like ("fancy pointer") argument.

This function, if defined, is the inverse of pointer_to, and exists as the customization point to be called by std::to_address.

Parameters

p

-

fancy pointer/pointer-like object

Return value

A raw pointer of the type element_type* that references the same memory location as the argument p

pointer_to [static]	obtains a dereferenceable pointer to its argument (public static member function)
to_address (C++20)	obtains a raw pointer from a pointer-like type (function template)
