Hi all, I'd like to use signal handling functions - alarm() and sigaction() within a format. Howver using them disrupts status checking, even if I restore to the previous signal handler after I'm done using signals. The sequence of function calls within the format is as follows: sigaction(SIGALARM, &set_signal, &old_signal); alarm(x); . . . alarm(0); sigaction(SIGALARM, &old_signal, NULL); But the above sequence fails to restore normal JtR signal handling. So, what's missing? Regards, Sayantan Content of type "text/html" skipped
