Description

>>> type_lib = bv.platform.get_type_libraries_by_name('ntdll.dll')[0]
>>> bv.import_library_object('LdrLoadDll', type_lib)

^ this returns None

This might be expected since iirc LdrLoadDll is not a documented API and might be missing from our data sources for the type library. Still, I am creating this issue to keep track of it since it would still be nice to have it

Research direction

Start by reproducing the ntdll.dll lookup with bv.platform.get_type_libraries_by_name and bv.import_library_object for LdrLoadDll. Inspect the type-library data sources and import path to determine whether this undocumented API can be represented; done means the import returns the LdrLoadDll definition from the ntdll type library.
