Description
bool 
com_print_typeinfo ( object comobject [, string dispinterface [, bool wantsink]] )
     The purpose of this function is to help generate a skeleton class for use
     as an event sink.  You may also use it to generate a dump of any COM
     object, provided that it supports enough of the introspection
     interfaces, and that you know the name of the interface you want to
     display.
    
     comobject should be either an instance of a COM
     object, or be the name of a typelibrary (which will be resolved according
     to the rules set out in com_load_typelib()).
     dispinterface is the name of an IDispatch
     descendant interface that you want to display.  If
     wantsink is TRUE, the corresponding sink
     interface will be displayed instead.
