61 "The libffi library provides a portable, high level programming interface
62 to various calling conventions. This allows a programmer to call any
63 function specified by a call interface description at run-time.
65 FFI stands for Foreign Function Interface. A foreign function interface is
66 the popular name for the interface that allows code written in one language
67 to call code written in another language. The libffi library really only
68 provides the lowest, machine dependent layer of a fully featured foreign
69 function interface. A layer must exist above libffi that handles type
70 conversions for values passed between the two languages.")
