(description
|
|
"The libffi library provides a portable, high level programming interface
|
|
to various calling conventions. This allows a programmer to call any
|
|
function specified by a call interface description at run-time.
|
|
|
|
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.")
