regarding expect_out(buffer)

Posted by sharmila (sharmila), 15 November 2005
 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.


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 dandelion
pingit dolphin
puts done

And that runs as

$ expect expog 64 bytes from icmp_seq=0 ttl=50 time=174.669 ms
dolphin: 64 bytes from icmp_seq=0 ttl=64 time=1.032 ms
