Smart pointers

Smart pointers enable automatic, exception-safe, object lifetime management.

Pointer categories
Helper classes


Allocators are class templates encapsulating memory allocation strategy. This allows generic containers to decouple memory management from the data itself.

Uninitialized storage

Several utilities are provided to create and access raw storage

C-style memory management

Includes e.g. std::malloc, std::free

Low level memory management

Includes e.g. operator new , operator delete , std::set_new_handler
