There is some support code for doing various Win32-related group/user analysis like this in cygwin's login package. The files you'd be interested in -- winsec.c and winpriv.c, along with test_winsec.c -- were written by Chris Rodgers, me, and I'm sure Corinna contributed a few patches along the way. Those three files are under slightly different licenses, but are MIT/X-ish. -- Chuck -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
