[Openmcl-devel] bug with usocket and/or trunk ccl - "error #22"

[Patrick Stein]

usocket from the current quicklisp dist is calling (ccl::inet-connect ...) with a few parameters it gets by calling other unexported CCL functions.

Just this line is sufficient to get to the (first?) problem:
> (usocket:socket-connect "localhost" 1111 :protocol ':datagram)


In a quick glance around trunk, I didn't see where make-udp-socket would invoke connect(2) or any way to do it after-the-fact.
