std::pointer_traits

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

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 of pointer_to , and exists as the customization point to be called by std::to_address .

Parameters

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 .
