Memory Management

Abstract

The STL provides facilities for memory management. These include the allocator class, the raw storage iterator, temporary buffers, the auto_ptr, and some utility functions. The allocator class is a general-purpose allocator that is the default allocator used by all the STL containers. The raw storage iterator is an object that can write values to uninitialized memory by first constructing the required object and then assigning a value. auto_ptr is a smart pointer that can be wrapped around a pointer to dynamically allocated memory so that the dynamically allocated memory is freed when the scope in which the auto_ptr is allocated is destroyed.
