By default AGENT++ is a multi-threaded agent. Therefore access to each MibEntry in the a Mib has to be synchronized.

As tables and complex (sub-tree) entries may contain also MibEntry objects, for example scalars, additional levels can be implemented by the user.
In any case, the locking procedure must start with the following steps:
