Yes - this is because it calls RegisterServiceCtrlHandlerEx on those platforms. > According to msdn, a HandlerEx function has to be used to get > callbacks. > This function should take 4 arguments : > DWORD WINAPI HandlerEx( > __in DWORD dwControl, > __in DWORD dwEventType, > __in LPVOID lpEventData, > __in LPVOID lpContext > ); > > But in fact it gets only one. > I've modified win32serviceutil to verify it : > def ServiceCtrlHandler(self, control) => def ServiceCtrlHandler(self, > control, *args) > > and : > def SvcOther(self, control, *args): > > *args still is an empty tuple (). I only get "dwControl", why don't I > get "dwEventType", "lpEventData" and "lpContext" (this last one is user > defined so it can be empty, but not the other two) ? It is because I took a bit of a shortcut, and when moving to RegisterServiceCtrlHandlerEx() I didn't work to allow for an alternative python callback that takes the additional args (and supplying them, as in the '* args' in your example, would break existing services). I'd be happy to add this though - contact me offline for the best way to arrange for this (and lpContext is used by the implementation, so if you have a specific use-case for this param, I'd like to know about that too) Cheers, Mark _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
