Hi there: I just decided to stop using signal() and start using sigaction(). The problem is that it neither references sigemptyset(), sigaddset(), or any of the other functions involved in manipulating the sigset_t structure under "SEE ALSO", nor does it explain that sa_mask is intended to be modified by those functions. That lack of clarity forced me to look up someone else's code as a reference. I'm using man-pages-3.23 & man-pages-posix-2003a under Gentoo. -Phil/CERisE -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
