Hi all, I have a C shared library exposing a simplified interface for computing message digests. Here's a `while` that reads bytes using a callback.
https://github.com/zyrolasting/xiden/blob/libcrypto/crypto/crypto.c#L46 A compatible callback provided by Racket might look like this. (λ (buf size) (let ([bytes-read (read-bytes! buf (sync variant))]) (if (eof-object? bytes-read) -1 bytes-read))) I'm also unsure if jumping between the Racket and C runtimes add much overhead, but I did it because it looks like `unsafe-port->file-descriptor` will only function as expected for file ports. Is there a cross-VM way to pass an arbitrary input port to the C runtime (e.g. via open-input-bytes), such that the C runtime can read bytes on its own? -- ~slg -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
