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 in the std namespace: These are the operator overloads for new and delete, which handle dynamic storage requests. Some of these functions have also the special property of being replaceable in a program.

The header also defines some specific types and the set_new_handler function:

operator new Allocate storage space (function)
operator new[] Allocate storage space for array (function)
