This week, we're updating our course layouts and descriptions. Presentation and materials always gently change over time, but just occasionally there's a need to make a step change to clear out some of the old and roll in the new. That's now happening - but over a long and complex site it's not instant and you'll see sections of the site changing up to and including 19th September.

regarding expect_out(buffer)

Posted by sharmila (sharmila), 15 November 2005
Hi,
 when i try to read the expect_out(buffer) from a procedure, it says can't read,no such variable exists.I have even declared the expect_out(buffer) as global inside the procedure.But it says no such variable.

You need to declare the whole of expect_out global rather than just one element.

Example

Code:
proc pingit what {
   global expect_out
   spawn ping -c 1 $what
   expect \n
   expect \n
   puts -nonewline "$what: $expect_out(buffer)"
   return 1
   }

log_user 0
pingit www.wellho.net
pingit dandelion
pingit dolphin
puts done


And that runs as

Code:
$ expect expog
www.wellho.net: 64 bytes from 64.62.240.12: icmp_seq=0 ttl=50 time=174.669 ms
dandelion:
dolphin: 64 bytes from 192.168.200.103: icmp_seq=0 ttl=64 time=1.032 ms
done
$
