# weak_ptr
|
|
|
|
`weak_ptr` is a smart pointer in C++ that holds a non-owning reference to an object managed by a `shared_ptr`. It doesn't participate in the object's ownership count, meaning that it doesn't prevent the object from being destroyed if the `shared_ptr`s owning the object go out of scope. Its primary use is to detect if the object managed by the `shared_ptr` still exists. You can obtain a `shared_ptr` from a `weak_ptr` using `lock()`, but this might return an empty `shared_ptr` if the object has already been destroyed. |
