If it's in the form where you start by writing along the lines of: import libffi then it must be something very different to what I looked at. (Which seemed to consists of lots of C files, headers and ASM modules, for dozens of different targets and compilers.) I would also expect a foreign-function interface to be built-in, or to have all the details taken care of by an add-on, so that the very low level libffi wouldn't figure at all. -- Bartc
