(C++) shared_ptr

 

 

shared_ptr is a type of smart pointer that can be copied safely and cheap, without copying the object pointed to. When the last shared_ptr using an object goes out of scope, it will delete the object pointedto.

 

There are multiple types of shared_ptrs:

• boost::shared_ptr
• std::tr1::shared_ptr
• std::shared_ptr
