Hello David,
dbuc> Thx. I've read that article but I can't find an dbuc> ExternalTypes class in my image. Do I need to load a particular dbuc> package to get NamedPrimitives or FFI to work?
maybe you are not aware of the fact that FFI and namedPrimitives are two independent ways to talk to external code.
To create named primitives you need to get the VMMAKER package, Cédrick replied on FFI.
As far as I know named primitives are a better choice if you need to call into a dll very often. You can put the loop which calls into the external code into the C- code you generate as a primitive and thus have less overhead.
All in all these are not really beginners topics, so maybe ask in SqueakDev.
