Re: Persistent User Defaults

[2551phil]

Agreed. Only one thing that I didn’t see mentioned yet is that when using 
defaults delete the targeted app should not be running.

last, getutxent & friends

[2551phil]

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(), 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(), 
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(), 
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

Re: Purge all remnants of an old incarnation of my app

[2551phil]

Normally, I just do 

defaults delete  

on the command line and that takes care of it. Issuing 

defaults domains

will give you a (comma-separated) print out of all the defaults domains on your 
mac.

“There’s an app for that” - have a look at PaintCode.

I did do exactly that for the legacy AppleScript stuff[1] when it started 
disappearing, but it’d be a bit of a mammoth task to do the same for the whole 
of the Cocoa APIs. The best alternative I found once Apple removed the PDFs was 
to use Dash[2].
