HSFFIG: Generate FFI import declarations from C include files

Haskell FFI Binding Modules Generator (HSFFIG) is a tool that parses C library include files (.h) and generates Haskell Foreign Functions Interface import declarations for all functions, #define'd constants (where possible), enumerations, and structures/unions (to access their members). It is assumed that the GNU C Compiler and Preprocessor are used. Auto-generated Haskell modules may be imported into an application to get access to the foreign library's functions and variables.

The package provides a small library that programs using auto-generated imports have to link to (specify HSFFIG as one of build-depends), and two executable programs:

• hsffig: a filter program reading pre-processed include files from standard input, and producing one large .hsc file to be processed by hsc2hs, and possibly cut into pieces by modsplit. See http://www.haskell.org/haskellwiki/HSFFIG/Tutorial for more information.

• ffipkg: a wrapper over hsffig which automates the process of building a Cabal package out of C include files provided by running the preprocessor, hsffig, the splitter, and preparing the files necessary to build a package. See http://www.haskell.org/haskellwiki/FFI_imports_packaging_utility for more information.

Please note that hsffig and ffipkg will likely not work properly with C++ include files.
