Hello. I have a code where i need more than one "wrong" pointer value(this one is NULL pointer). Something like a signal handler SIG_IGN that equal to 1. So, my question is, what is the guarantied range of addresses (from 0 to X), which can be safely used for this purpose on any hardware architecture? Thanks. -- Олег Неманов (Oleg Nemanov) -- To unsubscribe from this list: send the line "unsubscribe linux-c-programming" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
