Hi.

Are there any facility like below with-fixed-time in CL (esp SBCL)?

(defun foo()
  (with-fixed-time ( time-interval
         (setf s (make-socket))
         (connect-to-host s :host foo :port baz)
          ...
  ))

? (foo)
 - signal an error if the clauses of with-fixed-time does not end
   in given time-interval


After deciding to build simple network application in SBCL, I have met
too many walls. My life with CL is tough yet. :-(

TIA, Regards.

I'm afraid my question isn't clearly described.
The execution of clauses with with-fixed-time should be terminated at
given time-interval elapsed.

So (with-fixed-time (5 (loop))) must signal error after 5 seconds.

Give me an insight. TIA

Self-reply. shame on me.

sb-ext:with-timeout macro is the exact one i want.
(why I forgot apropos...)
Thanks to SBCL developers.

I show 48 minutes between your original query and your announcement of 
finding the fix on your own. Nothing to be ashamed of there. And, yeah, 
apropos is awesome.
