You want to use a tool to make all this easier. There are various tools available:
green-card, c2hs, and hsc2hs are the most commonly-used ones these days. Alastair
Reid wrote a good comparison of the various tools (can't remember the link off hand
though).
There are examples of hsc2hs code in the libraries - particularly
fptools/libraries/unix has examples of doing defines, enums and structs. Examples of
green-card stuff can be found in fptools/libraries/HGL and fptools/libraries/X11.
Take a look at Manuel's GtkHS for c2hs examples.
Cheers,
Simon
