Besides the high-level utilities described in Section 4.12, the OLE-Automation module also provides a C-FFI interface to the Microsoft OLE Automation API, as exposed through OLEAUTO.H, OLEAUT32.LIB, and OLEAUT32.DLL.
Note that the following names from the Microsoft OLE Automation API names are not supported, because they are considered obsolete:
INTERFACEDATA, METHODDATA, PARAMDATA, CreateDispTypeInfo
See Chapter 9, "OLE FFI Facilities", for details of the correspondence between the C/C++ names in the Microsoft OLE documentation and Dylan names in the Functional Developer OLE/COM FFI libraries.
