The process exit code is the return value from the process object's 
wait() function:

exitcode = proc:wait()
    

I'm not sure I understand... popen() doesn't return a process object, it
returns a file handle.  Also, I don't see wait() or a process object in
the lua docs anyplace.  Is it part of an add-on module?  I don't think
there's any concept of process in ANSI-C, which is what the un-adorned
lua interpreter targets.
  

I was responding to Steve Donovan's message about lua-ex.  See http://lua-users.org/lists/lua-l/2009-06/msg00135.html.
