[Pharo-users] uFFI: Calling conventions?

Hi all, I haven't found any information on calling conventions in the "Unified FFI - Calling Foreign Functions from Pharo" manual. What conventions are available, please? If the ThisCall[1] convention isn't supported, could it be implemented in code with some boilerplate? Thank you. -- [1] ThisCall works like StdCall, but the first parameter - the "this" pointer - is passed via the ECX register.
