socket-recv! not working - "make-sized-byte-string: unsupported" about zeromq HOT 4 CLOSED

That function is not supported in ChezScheme --- https://docs.racket-lang.org/foreign/foreign_pointer-funcs.html#%28def._%28%28quote._~23~25foreign%29._make-sized-byte-string%29%29

from zeromq.

Are there any plans to add compatibility to this project to support socket-recv! in ChezScheme?

from zeromq.

I have no plans and I assume that @mflatt can't support make-sized-byte-string. If you find a way to make something similar works, I'd merge it!

from zeromq.

It looks like the use here

 (make-sized-byte-string (msg-data-pointer m) (msg-size m))

could be replaced with

(let ([s (make-bytes (msg-size m))])
  (memcpy s (msg-data-pointer m) (msg-size m))
  s)

This copies data out of the message instead of pointing inside message. But socket-recv! was copying anyway, and the bytes-copy there could be removed.
