FFI stands for Foreign Function Interface. A foreign function interface
is the popular name for the interface that allows code written in one
language to call code written in another language. The libffi library
really only provides the lowest, machine dependent layer of a fully
featured foreign function interface. A layer must exist above libffi
that handles type conversions for values passed between the two
languages.
successfully tested on seven arches by me. other arches are disabled for now as
they need more work (mips64) or haven't been tested yet.
