I hope that I'm posting this to the correct list. Concerning CF, I was wondering if the following scenario is correct: A "parent" thread creates a child thread via the pthread library. The child thread has only 1 runloop source on it (a timer in fact), and once the timer is applied onto the child runloop by the child itself, the child proceeds to call CFRunLoopRun() on itself. Now the parent is responsible for running down this child on demand. Can the parent rundown the child by: I'm not sure what you mean by "rundown," but I'll assume you mean stop the child's runloop. It's my understanding that a RunLoop will stop running when it has no more valid sources or timers to listen to. So if there is only one timer in the run loop, either of these would accomplish your goal. -calling CFRunLoopIsWaiting() in a while loop until it returns true (which indicates that all callbacks have drained and that it is waiting again, but of course since the timer was invalidated it can never be called again). Of course I should NOT holding a resource which the callback might need in order to execute and exit. While I'm sure you could make something like this work, it's pretty contrived. -calling CFRunLoopStop() -calling pthread_join() on the pthread I don't think this will stop the run loop. Instead, it will block the parent thread until the child thread exits. Can this also be extended to other runloop sources, by using CFRunLoopSourceInvalidate() instead of CFRunLoopTimerInvalidate(), and CFRunLoopRemoveSource() instead of CFRunLoopRemoveTimer()? If these procedures are incorrect, why so, and what are the alternatives? I don't see any of the above as "alternatives." In your case, with only one runloop source, CFRunLoopTimerInvalidate(), CFRunLoopRemoveTimer(), and CFRunLoopStop() all have the same end- result. However, this is a consequence of a simple example, and not generally true. Invalidating and removing a source have different semantics. For example, you may want to invalidate a source (no matter how many runloops may be using it), or alternatively you may want to remove a source from a particular runloop but keep it as a source in another runloop (or perhaps add it back to the same runloop at a later time). Stopping a runloop doesn't affect any of the sources, so it can be restarted at a later time in the same configuration that it was in originally. This email sent to site_archiver(a)lists.apple.com

Relocation overflow ... displacement too large

The messages only refer to C and C++ object files, not to the Fortran code. This is a large finite element code that, unfortunately, we can't make a lot of changes to. I've seen some discussion about resizing static arrays but the standard answer is to recompile the code with the -mlong-branch option. Given that we've already recompiled it with -mlong-branch, can anyone suggest another option to get our code linked? Does anyone know if building shared (-fPIC) will affect this? Is this a bug in the linker? This email sent to site_archiver(a)lists.apple.com

Miredo and Darwin

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Hi, I am trying to get Miredo working with Darwin, but I am having problems. For me both the 'make check' fail and when running miredo the command just blocks. I don't have any experience with ktrace, so I am not too sure of how to interpret what is outputted. Has anyone tried this with Darwin? Has anyone any ideas. The links for Miredo, and tuntap are: miredo: http://www.simphalempin.com/dev/miredo/ tunap: http://www-user.rhrk.uni-kl.de/~nissler/tuntap/ Andre _______________________________________________ Do not post admin requests to the list.
