[Sbcl-devel] sb-bsd-sockets patch

[Jerry J. <log...@gm...>]

I'm doing a little socket programming.  I tried to use the CANONNAME
slot in the addrinfo structure, and got what appears to be the bytes
of the pointer interpreted as characters.  I think this patch is
needed:

  #+sb-bsd-sockets-addrinfo

Warning: I haven't actually tried rebuilding SBCL with that patch.

Also, I tried redeclaring the type at the prompt, hoping I could get
away with that.  What I got instead was a complaint that
sb-alien::*record-types-already-unparsed* is unbound.  Once I setq it
to nil, then I got the feared, but expected, notice that I was trying
to redefine a type with an incompatible definition.  Should that
variable have been bound to something already?
