Create C functions for embedded Racket CS

[dotoscat]

There are a function such scheme_make_prim_w_arity

for the CS version? The idea is to use Racket

as a scripting language for a C program.

Thank you.

That's what guile was designed for.
How does Racket measure up as a scripting language for C?

There's currently no support in the C API of Racket CS for constructing
a Scheme procedure that calls a C procedure. You have to work from the
Scheme side using `foreign-procedure` to create a wrapper for a C
function.
