I am reading the /var/adm/pacct file in binary mode, instead of using acctcom...for some application specific reasons from solaris 10 machine Everything goes file, but the uid, gid feilds always seem to be zero(root). Can anyone pls help me in knowing how to get the username information directly from pacct file. Am sorry for posting this here, as it related to process accounting but not DTrace. I couldnt get response from any other forums and the work is very urgent. Thanks and Regards, Arun DK. This message posted from opensolaris.org
