/*
* TYPELIB
*
* Copyright 1997 Marcus Meissner
* 1999 Rein Klazes
* 2000 Francois Jacques
* --------------------------------------------------------------------------------------
* Known problems (2000, Francois Jacques)
*
* - Tested using OLEVIEW (Platform SDK tool) only.
*
* - dual interface dispinterfaces. vtable-interface ITypeInfo instances are
* creating by doing a straight copy of the dispinterface instance and just changing
* its typekind. Pointed structures aren't copied - only the address of the pointers.
* So when you release the dispinterface, you delete the vtable-interface structures
* as well... fortunately, clean up of structures is not implemented.
*
* - locale stuff is partially implemented but hasn't been tested.
*
* - imported typelib should be stored together in a linked list instead of having
* independant TLBImpLib strucutures in each ITypeInfo. This way, imported libraries
* are just imported once (major optimization)
*
* - typelib file is still read it's in entirety, but it is released now.
* - some garbage is read from function names on some very rare occasion
*
* --------------------------------------------------------------------------------------
* Known problems left from previous implementation (1999, Rein Klazes) :
*
* -. Only one format of typelibs is supported
* -. Data structures are straightforward, but slow for look-ups.
* -. (related) nothing is hashed
* -. there are a number of stubs in ITypeLib and ITypeInfo interfaces. Most
* of them I don't know yet how to implement them.
* -. Most error return values are just guessed not checked with windows
* behaviour.
* -. didn't bother with a c++ interface
* -. lousy fatal error handling
* -. some methods just return pointers to internal data structures, this is
* partly laziness, partly I want to check how windows does it.
