This means that , if assmbler code is to be used in the handling routine, the remaining registers (?) must be saved beforehand and restored afterwards. what does the author mean by registers modified by a normal C function, and the remaining registers? - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
