Module documentation for 0.25.2

There are no documented modules for this package.

`c2hs` is a interfacing tool that eases Haskell access to C libraries.
The tool gets information about the C data type definitions and
function signatures by analysing the C header files of the library.
It uses this information to compute the missing details in the
template of a Haskell module — called the binding file —
that implements a Haskell binding to the C library. Hooks embedded in
the binding file signal where, which, and how C objects are accessed
from Haskell. The Haskell code in the binding file determines Haskell
types signatures and marshaling details.

Further information is on the
[wiki](https://github.com/haskell/c2hs/wiki/Home). Also see the
[user guide](https://github.com/haskell/c2hs/wiki/User-Guide) (also
available in the `doc` directory of the repository).

after all import hooks anyway

-i flag which takes a colon separated list of search paths for
.chi files.

* fixed some bugs in parsing import hooks

2001-05-13 Manuel M. T. Chakravarty <chak@cse.unsw.edu.au>

* toplevel/Version.hs (versnum): 0.9.5

* gen/GenBind.hs (expandHook): revised to properly handle struct,
union, and enum tags as C identifiers in pointer hooks; also
handles non-abstract pointers with explicit "*" now better; the
problems were pointed out by Marcin Kowalczyk <qrczak@knm.org.pl>

* c/CTrav.hs (findTypeObjMaybe): added
(lookupDeclOrTag): added
(enumName): added
(tagName): added

* toplevel/Version.hs (versnum): 0.9.4

2001-05-06 Manuel M. T. Chakravarty <chak@cse.unsw.edu.au>

* toplevel/Version.hs (versnum): 0.9.2

2001-05-02 Manuel M. T. Chakravarty <chak@cse.unsw.edu.au>

* gen/GenBind.hs (extractCompType): as pointed out by Axel Simon,
we can't return `ForeignPtr's from imported foreign functions
(setGet): the `accessType' story is largely redundant with the new
formulation of `extractCompType', but we still need to check the
marshaled type
(setGet): `DefinedET' now takes a declaration rather than an
identifier as its first argument; this is necessary for anonymous
declerators
(extractCompType): functions are now extracted correctly

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

* gen/GenBind.hs (extractCompType): completely rewrote this
function to properly handle pointer and function types and honour
aliases introduced by pointer hooks

2001-05-01 Manuel M. T. Chakravarty <chak@cse.unsw.edu.au>

* c/CTrav.hs (isPtrDeclr): functions types without an explizit
pointer constructor are no longer regarded as pointers

`CFunPtrPT', respectively

* gen/GenBind.hs (extractCompType): revised for pointer hooks

2001-04-30 Manuel M. T. Chakravarty <chak@cse.unsw.edu.au>

* gen/GenBind.hs: clean up

2001-04-21 Manuel M. T. Chakravarty <chak@cse.unsw.edu.au>

`deriving' option for the `enum' hook. This code was contributed
by Axel Simon <simona_@web.de> (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 <simona_@web.de>

* gen/GenBind.hs: The following patch was contributed by Axel
Simon <simona_@web.de>: `extractCompType' generates addresses
of type `Ptr <type>' instead of `Addr' (if `--old-ffi=no', which
is the default)

* configure.in: Adapted for ghc 5.00

* toplevel/Version.hs (versnum): 0.9.0 "Blue Ginger"

compilation and linking

2001-02-13 Manuel M. T. Chakravarty <chak@cse.unsw.edu.au>
