Module documentation for 0.28.8

There are no documented modules for this package.

C->Haskell assists in the development of Haskell bindings to C libraries. It extracts interface information from C header files and generates Haskell code with foreign imports and marshaling. Unlike writing foreign imports by hand (or using hsc2hs), this ensures that C functions are imported with the correct Haskell types.

we can't return `ForeignPtr's from imported foreign functions
(setGet): the `accessType' story is largely redundant with the new

marshaled type

identifier as its first argument; this is necessary for anonymous
(extractCompType): functions are now extracted correctly

* c/CTrav.hs (isPtrDecl): works on identifiers now and chases
(dropPtrDeclr): added

function to properly handle pointer and function types and honour
aliases introduced by pointer hooks

pointer constructor are no longer regarded as pointers

`deriving' option for the `enum' hook. This code was contributed
by Axel Simon <> (also related code in CHSLexer.hs);
but added parenthesis to `deriving'

* c/CTrav.hs: Added code implementing the `alias' hook, which
was contributed by Axel Simon <>
