bsl::weak_ptr::weak_ptr

Declared in <bslstl_sharedptr.h>

Create a weak pointer that refers to the same object (if any) as the specified other weak pointer of the (template parameter) COMPATIBLE_TYPE, and increment the number of weak references to the object managed by other (if any). If COMPATIBLE_TYPE * is not implicitly convertible to ELEMENT_TYPE *, then a compiler diagnostic will be emitted. Note that if other is in the empty state, this weak pointer will be initialized to the empty state.
