What is a type library, and how is it used?

A type library is a binary description that includes interface properties and methods, and method arguments.
Type libraries are used in situations when high-performance development languages, such as Visual Basic 6.0, need to be able to access interface methods directly, through the vtable. To make this possible, type libraries provide the Visual Basic client with information on which data types are required by the interface
methods.
