1.0 Introduction

1.1 Project/Component Working Name:

    libffi - Foreign Function Interface library
    
1.2 Purpose

    The Foreign Function Interface library facilitates calling code
    written in one language from code written in another language.
    See http://sourceware.org/libffi/ for more information.

    The purpose of including it in OpenSolaris is the ctypes Python
    modules.  The ctypes module (in Python 2.5 and later) provides
    C compatible data types, and allows to call functions in shared
    libraries.  Ctypes uses libffi.
    
    See http://docs.python.org/lib/module-ctypes.html for more
    information about ctypes.
