C->Haskell is an interface generator that simplifies the development of Haskell bindings to C libraries. The tool processes existing C header files that determine data layout and function signatures on the C side in conjunction with Haskell modules that specify Haskell-side type signatures and marshaling details. Hooks embedded in the Haskell code signal access to C structures and functions -- they are expanded by the interfacing tool in dependence on information from the corresponding C header file.
Haskell 98 is "the" standard lazy functional programming language. More info plus the language definition is at http://www.haskell.org/.
