What is libffi?

+ +Compilers for high level languages generate code that follow certain +conventions. These conventions are necessary, in part, for separate +compilation to work. One such convention is the "calling +convention". The "calling convention" is essentially a set of +assumptions made by the compiler about where function arguments will +be found on entry to a function. A "calling convention" also specifies +where the return value for a function is found. + +

+ +Some programs may not know at the time of compilation what arguments +are to be passed to a function. For instance, an interpreter may be +told at run-time about the number and types of arguments used to call +a given function. Libffi can be used in such programs to provide a +bridge from the interpreter program to compiled code. + +

+ +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. + +

Supported Platforms and Prerequisites

+ +Libffi has been ported to: + + + +Libffi has been tested with the egcs 1.0.2 gcc compiler. Chances are +that other versions will work. Libffi has also been built and tested +with the SGI compiler tools. + +If you port libffi to another platform, please let me know! I assume +that some will be easy (x86 NetBSD), and others will be more difficult +(HP, AIX). + +

Authors & Credits

+ +Libffi was written by Anthony Green. +

+Portions of libffi were derived from Gianni Mariani's free gencall +library for Silicon Graphics machines. +

+The sparc port was derived from code contributed by the fine folks at +Visible Decisions Inc. Further enhancements were made by Gordon Irlam at Cygnus Solutions. +

+The Alpha port was written by Richard Henderson at Cygnus Solutions. +

+Andreas Schwab ported libffi to m68k Linux and provided a number of +bug fixes. +

+Geoffrey Keating ported libffi to the PowerPC. +

+Raffaele Sena ported libffi to the ARM. +

+Jesper Skov and Andrew Haley both did more than their fair share of +stepping through the code and tracking down bugs. +

+Thanks to Tom Tromey for bug fixes and configuration help. +

+Thanks also to Jim Blandy, who provided some useful feedback on the libffi +interface. +

+If you have a problem, or have found a bug, please send a note to +green@cygnus.com. + + +
