Message-Id: <20141212230117.D71362C3A73@topped-with-meat.com> Date: Fri, 12 Dec 2014 15:01:17 -0800 (PST) X-CMAE-Score: 0 X-CMAE-Analysis: v=2.1 cv=SvUDtp+0 c=1 sm=1 tr=0 a=WkljmVdYkabdwxfqvArNOQ==:117 a=14OXPxybAAAA:8 a=kj9zAlcOel0A:10 a=hOe2yjtxAAAA:8 a=mDV3o1hIAAAA:8 a=r0hJhu78S7YiXseJKo4A:9 a=CjuIK1q_8ugA:10 These four are nonstandard functions for which the only implementations are pure Linuxism. I've added ENOSYS stubs that are OS-generic. The getname/setname interface could be implemented "generically" to just store and fetch the name locally, but that is probably not of much use.
