Greetings,
I am trying to send a racket cvector to a C function in a lib I a
writing. The C function in question has the prototype
void render(int x_camera, int y_camera, Visual pc, Tile **world);
The important bit is the last argument, Tile **world. I have
registered this in racket as
(define render
(get-ffi-obj "render" cio
(_fun _int _int _visual (_ptr i _cvector) -> _void)))
Unfortunately, whenever I try and send a cvector of type Tile into it,
I get the error
SIGSEGV MAPERR si_code 1 fault on addr 0x100004
I am confident it is due to this, since it executed flawlessly until I
expanded the function to receive the cvector.
Can anyone point out where I might be going wrong? Will be happy to
paste the whole thing up in gist or similar.
Thanks,
Lewis
