conditionally move one level down the inheritance hierarchy

Synopsis
| #include <«pkg»/«Mod».h> «Mod»_Handle «Mod»_Handle_downCast(«IMod»_Handle handle); |
Description
This function is automatically defined for all target modules that support instances and inherit from an interface, where «Mod» is the name of some module and «IMod» is the name of some interface. This function converts an abstract interface handle to an instance handle managed by the concrete module «Mod». If handle does not actually reference an instance managed by «Mod», «Mod»_Handle_downCast() returns NULL.
