I think PyRun_String is similar to exec. If you are on a Unix system you
can use the alarm signal. Here is a pure Python example, but I suspect
you can translate this to C in a straightforward manner.
import signal
class AlarmError(Exception):
pass
def handler(signum, frame):
raise AlarmError, "command lasts too long"
signal.signal(signal.SIGALRM, handler)
def execute(command, timeout):
signal.alarm(timeout);
try:
exec(command)
except AlarmError, e:
print e
print 'Aborted "%s"' % (command,)
print "continue work"
print "The everlasting command"
execute("while 1: pass", 10)
print "The End"
