If the UUID's don't match, you can alert the user and rebuild whatever it is you're doing. What you need to track is the UUID of the FSEventStore, together with the last event ID. That is, there are three relevant IDs: The volume itself has a UUID Each volume has its own FSEventStore, with its own UUID There is an event ID, that is meaningful only with respect to its particular FSEventStore The FSEventStore gets invalidated and discarded at the slightest hint of trouble; most commonly any time the volume is not unmounted properly. A system crash, of course, fails to unmount any volume correctly, so it invalidates the FSEventStores of all volumes mounted at the time. A full OS install seems to also invalidate the FSEventStore. The volume's UUID persists across all those things, but not across an erase. You can use it to be sure you're referring to the proper volume. You can get the volume's UUID from diskutil info. You can read the FSEventStoreUUID from /.fseventsd/fseventsd-uuid FSEventsCopyUUIDForDevice is the correct way to read the event store UUID. - m -Ron Hunsinger ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Instantly delete a directory without recursion?
If you unlinked just the top-level directory node, you would leave all of its descendents with a link count 0, and the corresponding blocks claimed by the descendents would never be freed. (Ever. No one would have a reference to them, and they'd never be found in subsequent traversals.) To regain the space, you have to traverse through the structure and decrement the link count of the children of the tree.

Re: Safe frameworks for privileged tools?
Yes, it's a helper tool. It runs for a couple of seconds (under normal conditions) and exits immediately. It interacts with the file system by reading information about some directories, so its launched duration is, of course, bound to the responsiveness of the hard drive on which it's operating. As such, a couple of seconds might be five or ten seconds on machines where the drive is spinning up, otherwise busy, etc. It's certainly possible that someone might invoke fast user switching right in the middle of the tool running, but it's /probably/ not an issue. I'm still not quite convinced it isn't, just yet. I need to do more thinking about it. The discussion so far has been very helpful. As far as connecting to the window server goes, Apple states: http://developer.apple.com/technotes/tn2005/tn2083.html#SECWINDOWSERVER Apple plans to disable the global window server service in a future release of Mac OS X. Do not write any new code that uses the global window server service. So when you say default window server, are you speaking of the global window server, or the default window server associated with the current console session? -- m-s On 23 Apr, 2008, at 13:04, stephen joseph butler wrote: On Wed, Apr 23, 2008 at 11:42 AM, Dave Camp [EMAIL PROTECTED] wrote: Unless I'm reading the OP wrong, he's writing a privileged helper tool, not a daemon. Given that, I don't think the above documents are applicable. None of what I know is official, but just gathered and extrapolated from years of reading information about this. So I might be wrong... who knows. The unsafe frameworks make connections to the default window server. As a program launched from Finder/Dock/et al, this will always work as expected. Launched from ssh or root, there are some caveats. For ssh, they will work fine as long as the same user is logged onto the GUI. As soon as the user logs out, your program loses its connection and might crash. For root, they will work as long as the console user stays the same. If someone uses fast user switching, or logs out, then the program's connection changes and it might crash. In any event, none of the unsafe frameworks are documented as working in any conditions other than the normal ones. People may get them to work 90% of the time under other conditions, but that's unsupported and may change. So unless DTS tells you otherwise, I'd stay away. But that's me... maybe 90% is good enough for you. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Safe frameworks for privileged tools?
Hey all, I'm writing a privileged helper tool that at one point needs to determine if a given directory is a package. Normally, I'd use NSWorkspace, but that's part of AppKit, which is tied to Window Server. I don't link to AppKit in my privileged tool, so I don't get the oh-so-convenvient -isFilePackageAtPath: method. I would like to use LaunchServices for this, but wasn't sure if it was kosher to link to ApplicationServices.framework from a privileged tool. Are there guidelines as to which frameworks should and shouldn't be used in privileged tools? I know nothing can ever be safe, but some are surely more dangerous than others, and I'd love some guidance. -- m-s ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Determining which sheet closed with panels in separate nibs
Inside of MainMenu.nib, I have my application's main window. Also in MainMenu.nib is an NSObject subclass instance that is the main window's delegate. In another nib, I have a panel and an NSObject subclass instance that is the panel's delegate. The panel is opened attached as a sheet to the main window. When the sheet is closed on the main window, I need to do some things, so I implement -[NSWindow windowDidEndSheet:] in the main window's delegate. The problem is that I have other panels I attach as sheets to this window in different situations, and I need to distinguish between them so I take the correct action for the specific sheet that has closed. Normally, I'd just compare one outlet to another, but the panel itself is in another nib, and as such I can't hook it up to an outlet in the main window delegate.

Re: usleep()
Yes. Code in a method executes on a thread in order from top to bottom
(taking into account flow control from while/do/etc). The usleep()
function pauses the thread until the specified duration of time
passes, at which point the next line of code is executed.
And remember that the thread sleep duration is only approximate. You
aren't guaranteed exactly any number of microseconds due to processor
timing delays. Don't rely on the specified duration being 100% accurate.

16) i search usleep() in Xcode documentation, it explain that
suspend thread execution for an interval measured in microseconds.
Does it just mean it will stop the the code for how many microseconds?
- (IBAction)play:(id)sender {
iTunesApplication *iTunes = [SBApplication
applicationWithBundleIdentifier:@com.apple.iTunes];
if ( [iTunes isRunning] ) {
int rampVolume, originalVolume;
originalVolume = [iTunes soundVolume];
[iTunes setSoundVolume:0];
[iTunes playOnce:NO];
for (rampVolume = 0; rampVolume originalVolume; rampVolume +=
originalVolume / 16) {
[iTunes setSoundVolume: rampVolume];
/* pause 1/10th of a second (100,000 microseconds) between
adjustments. */
usleep(10);
}
[iTunes setSoundVolume:originalVolume];
}

Re: get currently logging in users
Why not peruse the sources of the who utility and see how it finds the data you want? http://www.opensource.apple.com/darwinsource/10.5/shell_cmds-116/who/ -- m-s On 13 Mar, 2008, at 22:27, lazuardi wrote: On 2008/03/14, at 10:51, Kyle Sluder wrote: who (and last) use wtmp and utmp. man utmp(5) for info on how you can access this information in your own programs.

Re: get currently logging in users
First, seconding what others are saying. This is not the right list for your problem if you go into the low-level APIs. The main difference between tiger and leopard's who source is the use of utmp and utmpx. utmp has been deprecated on leopard. leopard uses utmpx to retrieve currently logging in users. utmp uses at tiger is buggy? It's just limited. It's pretty easy to spot the difference in this regard, no guessing needed: the size of the ut_name member of the utmp struct is defined as 8 bytes. In the utmpx struct, however, you'll find that the size of the ut_user member is defined as 256 bytes. The old struct could only hold the first eight characters of the short name, while the one preferred under Leopard can hold very long short names. -- m-s ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: how to get a particular icon from .icns file
if you look at the count of representations of that NSImage, you will find several sizes. (Assuming, of course, that the original .icns file contained multiple representations of different sizes.) -- m-s On 09 Mar, 2008, at 09:28, Nick Rogers wrote: Hi, I have a icon file (.icns) with 10 icons in it and i want to create an NSImage with only the 32x32 icon from this file. Currently I'm doing: NSImage *anIcon = [[NSImage alloc] initWithContentsOfFile:iconPath]; which results in a very big 128x128 icon.
