pointer_traits::to_address
(哋它亢++20)(optional)
 
Defined in header <memory>
static element_type* to_address( pointer p ) noexcept;
 (since 哋它亢++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 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.
