An example will help (I am slower than usual today :-) Read the getcap(3) manpage. A simple example: foo: :bar#33:baz: fish: :zog#1:bar@:tc=foo: Retrieving the 'foo' entry gives the capabilities: bar = 33 baz = true Retrieving the 'fish' entry gives the capabilities: zog = 1 baz = true ie. the presence of the 'bar@' entry in 'fish' suppresses the 'bar' capibility when 'foo' is included. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
