Re: [Chicken-hackers] incorrect warning during compilation

[Kristian Lein-Mathisen]

I am watching these patches with great interest. They are surprisingly small, nice and comprehensible :)

I think this is a really nice foreign-type extension! And it's backward-compatible, right?

(let ((str "xBC"))

  ((foreign-lambda* c-string (((scheme-pointer unsigned-char) x)) "x[0] = 65; return(x);")

   str)

  (print str))

which produces

unsigned C_char *x=(unsigned C_char *)C_data_pointer_or_null(C_a0);

x[0] = 65; return(x);

which prints

ABC

I'm happy and would love to see this committed somewhere :)

Here is an attempt at Moritzens proposal.
