c - Detect stop process Python -

i have c program. want run , stop @ specific points, , allow python script things while stopped.

what did set line @ stopping points in c program:

kill(getpid(), sigstop);

if python code has line:

subprocess.call("./prog");

it stuck forever, because c programme never terminated.

if utilize this:

subprocess.popen("./prog");

it resumes before code section done.

how can check if subprocess stopped? or there solution? of import me maintain c programme running.

thank you, marina

i don't know what's purpose, if want check subprocess' status, utilize popen.poll(), if want wait stop, utilize popen.wait().

or need check status periodically? if so, seek threading.timer().
