std::pointer_traits

Member functions
pointer_traits::pointer_to (C++11)
pointer_traits::to_address (C++20)(optional)

[edit]

Defined in header`<memory>`
static element_type* to_address( pointer p)noexcept;		(since C++20) (optional member of program-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 ofpointer_to, and exists as the customization point to be called bystd::to_address.

[edit]Parameters

fancy pointer/pointer-like object

[edit]Return value

A raw pointer of the typeelement_type* that references the same memory location as the argumentp.

[edit]See also

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