I have a test harness (written in Python) that needs to shut down the program under test (written in C) by sending it ^C. On Unix, proc.send_signal(signal.SIGINT) works perfectly. On Windows, that throws an error ("signal 2 is not supported" or something like that). I am using Python 2.7 for Windows, so I have the impression that I should be able to do instead proc.send_signal(signal.CTRL_C_EVENT) but this doesn't do anything at all. What do I have to do? This is the code that creates the subprocess: # Windows needs an extra argument passed to subprocess.Popen, # but the constant isn't defined on Unix. try: kwargs['creationflags'] = subprocess.CREATE_NEW_PROCESS_GROUP except AttributeError: pass proc = subprocess.Popen(argv, stdin=open(os.path.devnull, "r"), stdout=subprocess.PIPE, stderr=subprocess.PIPE, **kwargs) Continue reading...
