[Haskell-cafe] C global vars local to threads

[Maurí­cio]

I would like to write a wrapper to C global
variable, but that variable is unique to each
thread. Is there some native support on that
in Haskell FFI?

(I imagine I probably should write a C function
to get its pointer as an 'IO (Ptr ...)', but I
would like to check if there's a more standard
way to do that.)

Thanks,
Maurício
