Defines several types and functions that control the allocation and freeing of storage under program control. It also defines components for reporting on storage management errors.
Header: <new>
Namespace: std
Some of the functions declared in this header are replaceable. The implementation supplies a default version, whose behavior is described in this document. A program can, however, define a function with the same signature to replace the default version at link time. The replacement version must satisfy the requirements described in this document.
