<new>
The latest version of this topic can be found at <new>.
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.
Syntax
#include <new>
Remarks
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.
Objects
| nothrow | Provides an object to be used as an argument for the nothrow versions of new and delete. |
Typedefs
| new_handler | A type that points to a function suitable for use as a new handler. |
Functions
| set_new_handler | Installs a user function that is called when new fails in its attempt to allocate memory. |
Operators
| operator delete | The function called by a delete expression to deallocate storage for individual of objects. |
| operator delete[] | The function called by a delete expression to deallocate storage for an array of objects. |
| operator new | The function called by a new expression to allocate storage for individual objects. |
| operator new[] | The function called by a new expression to allocate storage for an array of objects. |
Classes
| bad_alloc Class | The class describes an exception thrown to indicate that an allocation request did not succeed. |
| nothrow_t Class | The class is used as a function parameter to operator new to indicate that the function should return a null pointer to report an allocation failure, rather than throw an exception. |
