<div dir="ltr">Hello Doctor Yoo,<div><br></div><div>I am having serious problems with the Racket FFI. Apparently, to load a struct from a library, I have to know all of it's contents, and then define them in terms of their contents, until everything has been defined in terms of C primitives. Surely I am incorrect. Can you explain this to me? What do I do if the struct I need has 200 struct pointers in it, each of which points to 200 more, and so on, a couple of layers deep? </div>
