50 longDescription = ''
51 The libffi library provides a portable, high level programming
52 interface to various calling conventions. This allows a
53 programmer to call any function specified by a call interface
54 description at run-time.
55
56 FFI stands for Foreign Function Interface. A foreign function
57 interface is the popular name for the interface that allows code
58 written in one language to call code written in another
59 language. The libffi library really only provides the lowest,
60 machine dependent layer of a fully featured foreign function
61 interface. A layer must exist above libffi that handles type
62 conversions for values passed between the two languages.
