Subject: Updates system library calls: interface changes (removed unused parameters).
X-Git-Tag: v3.1.0~494
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/man.named.html?a=commitdiff_plain;h=748b3dd434a375e58e51bf99e1715f5518041b9b;p=minix.git

Updates system library calls: interface changes (removed unused parameters).
Removed old notification trap: renamed alert() to notify() ... finally ;-)
