longDescription = ''
|
|
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.
