BTW. This is the 2nd (that I know of) place where passing errors as strings is implemented (the other one is GEOM). This would be cool at some point to implement general API for this, as it's much more useful than errno(2). Of course we need to consider things like localization, etc. then. IIRC phk@ was talking about this at BSDCan. -- Pawel Jakub Dawidek http://www.wheel.pl [EMAIL PROTECTED] http://www.FreeBSD.org FreeBSD committer Am I Evil? Yes, I Am!
