I want to run ngspice through a xterm window in an application written in PyQt4. But I am not able to capture the exit signal of the ngspice process. I learned how to do the same for unix shell commands from the following link. But when I replace the shell command with ngspice, then the exit code is not getting propagated.

How do I get the exit code of command and not xterm?

It will do (tested in a CYGWIN64 console window under MS Windows):

$ xterm -e sh -c 'ngspice ; echo $? > echo_status.txt'

ngspice opens up. Terminate ngspice with

quit 33

Then enter

cat echo_status.txt

to the console window, and the answer will be

33
