annotate xwrited-debug.c @ 3:6e2d746b06ae

Support FreeBSD > 9.0 FreeBSD 9.0 introduced a new utmpx.h interface and using utempter is no longer possible or necessary. Adding entries to or removing them from the utmp database still requires elevated privileges, the base system provides a utempter-compatible interface with libulog which xwrited now makes use of.
