Dynamic memory

This header describes functions used to manage dynamic storage in C++.

Exceptionally within the standard library, this header declares several functions in the global namespace instead of within the std namespace: These are the operator overloads for operator new and operator delete, which handle dynamic storage requests. Some of these functions have also the special property of being implicitly declared and replaceable.

The header also defines some specific types and the set_new_handler / get_new_handler pair of functions:

operator new[]

operator delete

set_new_handler

get_new_handler
