[Ecls-list] gethostname, machine-instance & friends

[David_Creelman at pa.com.au]

Hi,
There is a similar problem with CLX and hostname.
By default (before the patch I submitted got put in) it looked at
machine-instance and failed too.
There should be a socket implementation in ECL anyway. Will that work?
Regards
David

Thanks for telling me about usocket.
The whole story is that I wanted to make cl-smtp work with ECL. The
CVS version of cl-smtp does not have code for ECL. I thought that it
would be easy to make it work since ECL has a socket package similar
to SBCL's. cl-smtp has implementation-specific code in files named
after each implementation. I started to copy sbcl.lisp to ecl.lisp and
then I noticed the use of (sb-unix:unix-gethostname). This is why I
sent my message in the  first place.
Now I saw in the change log that you recently made changes to usocket
with respect to cl-smtp:  "Add cl-smtp 'requirement': get-host-name
(ECL backend)."
So this is good news for me ! I guess I only have to tell cl-smtp to
use usocket isn't it ? How can I do that ?

Thibault

PS: I am not with my development machine right now so I did not tried
to use usocket yet.
