I have code that calls (with easyffi) a C library function. One
argument is a function. I've defined, with define-external, the
scheme function play. I pass a pointer to play to the C library
function with (location play). This breaks if play is not
I just want to take a moment in the midst of my FFI
confusion/annoyance to praise Chicken for the fact that something
like easyffi *exists at all*. I know just enough about C to have
some idea of just how *insanely* hard such a thing must be to make
work. Kudos!

I'm looking at using CDK (the widget library for ncurses) for a TUI

My primary question is, how should I be doing FFI to make it nice

Did you try using process-fork to create the process, as Felix
