Note that prior to your message I knew nothing about the utmp file... But after reading the man page for seutxent() and getutxent() and checking the utmp contents with dump-utmp on my laptop, I'm sure the problem is that with setutxent() you set the read pointer to the beginning of the file. The utmp file contains many entries, so you get just the first one, which happens to be an entry for the "reboot" user, which has nothing to do with the current user. To get the current user ID, you can use getuid() or geteuid(), whichever is more relevant for your purpose. getpwuid() can be used to get the user name corresponding to the numeric user ID. > Who is the “reboot” user? I don't know. -- Tanu _______________________________________________ IVI mailing list [email protected] https://lists.tizen.org/listinfo/ivi
