For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
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.

Posted by admin (Graham Ellis), 16 November 2005
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
$
