<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.

Requirements

Header: <new>

Namespace: std

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.

Members

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.
hardware_constructive_interference_size
hardware_destructive_interference_size

Functions

get_new_handler
launder
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.

Enums

align_val_t

Classes

bad_alloc Class The class describes an exception thrown to indicate that an allocation request did not succeed.
bad_array_new_length Class
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.
