Hi Everyone,

I've recently started working on Haskell FFI Tutorial [1]. The repository already

contains code that explains how to:

* (expressively) represent C `struct` in Haskell code

* call C code from Haskell

* call Haskell code from C

* operate on nested `struct`s

* operate on `struct` arrays

* decode `unions`

* read and write C fixed-length strings and Pointer-type Strings

* how to import functions from, for example, stdlib

I'm still working on more story-like writeups, but the first one (about how to call Haskell

from C) is already available [2].

If you have any feedback / comments / questions, know how to improve it or

would like to see more things covered, just ping me.

Thanks
