I'm trying to get this invocation right, and it is escaping me. How
can I capture the stdout and stderr if I launch a subprocess using
subprocess.check_call()? The twist here is that the call is running
from within a Windows service.
I've tried:
check_call("mycmd.exe", stdout=subprocess.PIPE) [raises an exception
"An integer is required"]
mycmd.exe isn't open (running). the mycmd.exe is supposed to be a fn.
How did you start it?
check_call("mycmd.exe", stdout=file("c:\\temp\\foobar.txt", "w"))
[raises an exception "An integer is required"]
==============
I think you need to run the .exe from your .py using the subprocess
module's commands and hook in at that time to stdin, stdout, ....
get the fn and use check_call() to see if .exe has something to say.
Check subprocess's help/man and so forth.
I know that if you start a program via os.Popen2's popen3 things work as
expected. How you would redirect I/O in an arbitrary already running
program in Windows is a good question.
