| Create a node proctor object that will use the specified list `listPtr` to free the specified `nodePtr`. The behavior is undefined unless `nodePtr` was allocated by the allocator of `*listPtr`.
| xref:bsl/List_NodeProctor/2destructor.adoc[`~List_NodeProctor`] [.small]#[destructor]#
| Destroy this node proctor, and free the node it contains unless the `release` method has been called before. Note that the `d_value` field of the node is not destroyed.
| xref:bsl/List_NodeProctor/release.adoc[`release`] 
| Detach the node contained in this proctor from the proctor. After calling this `release` method, the proctor no longer frees any node upon its destruction.
