signal.getsignal() or signal.signal() return the current/previous handler as a Python function. How could it return a reference to a native (i.e. C) signal handler? While we could in theory return it as a magic cookie (i.e. the handler's address as returned by sigaction/signal) that can just be passed back to signal.signal(), it would be a bad idea: if the user passes an invalid address, the process will crash when the signal is received. ---------- nosy: +neologix _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13285> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
