Apologies in advance as this is only indirectly a Cocoa question (in that I’m
trying to incorporate this data into my Cocoa app). Suggestions for a more
suitable home for this question are welcome.
My app needs to display the login and logout times of all users on the mac (for
macos 10.10 onwards). I’ve been playing with last and getutxent(), but I’m
finding them very unreliable. last appears to roll over a new wtmp file quite
at random, and often just as soon as I call it (via NSTask), giving me no info
at all.
getutxent() doesn’t seem to record the last logout time of the current user at
all. When I log out of my current session and call getutxent() after logging in
again, I don’t get the last logout time (I also tried lastlogx, but that just
kept returning NULL).
Here’s what I’m using for getutxent():
struct utmpx *bp;
time_t time;
setutxent_wtmp(0);
while ((bp = getutxent()) != NULL)
{
time = (time_t) bp->ut_tv.tv_sec;
switch (bp->ut_type)
{
case USER_PROCESS:
NSLog(@“\nUSER_PROCESS (login): %s\t%s\t%d\t%hd\t%s\t%s\t%s\t\n", bp->ut_user,
bp->ut_id, bp->ut_pid, bp->ut_type, ctime(&time), bp->ut_host, bp->ut_line);
break;
case DEAD_PROCESS:
NSLog(@“\nDEAD_PROCESS (logout):
%s\t%s\t%d\t%hd\t%s\t%s\t%s\t\n", bp-
>ut_user, bp->ut_id, bp->ut_pid, bp->ut_type, ctime(&time),
bp->ut_host, bp->ut_line);
break;
case LOGIN_PROCESS:
NSLog(@“\nLOGIN_PROCESS (?):
%s\t%s\t%d\t%hd\t%s\t%s\t%s\t\n", bp->ut_user,
bp->ut_id, bp->ut_pid, bp->ut_type, ctime(&time),
bp->ut_host, bp->ut_line);
break;
default:
break;
}
}
endutxent();
Does anyone know of a reliable way to get users' last logout times?
TIA
Phil
