Reference to ITypeInfo Object

Description

This is used to get the C-level representation of an ITypeInfo object. Currently, one gets this from the ITypeLib or from a COMIDispatch-class object. From this object, one can query the meta-information it contains such as method definitions, etc.

Usage

getTypeInfo(obj, which)

Arguments

obj	the object from which to get the ITypeInfo object.
which	the index (1-based) of the element within the ITypeLib whose ITypeInfo object is desired. If this is omitted, all the elements in the type library are returned.

Value

An object of class ITypeInfo which contains a slot giving the address of the C-level object representing the ITypeInfo object.
