I'm trying to compile mount_smbfs (from the tar.gz posted at http://www.opensource.apple.com/darwinsource/tarballs/other/smb -115.1.tar.gz) from the Xcode project, but I'm just getting hoards of errors claiming that Security/SecKeychainAPI.h doesn't exist and large amounts of non-existent constants as a result. And indeed, there is no SecKeychainAPI.h in the Security framework. So where is this thing? it's not part of darwin, you need to patch the project in order to build it.

AFAIK the ability to include a password in an SMB URL is Apple-specific, so I'd look for code guarded by Apple ifdefs :) Same ifdefs may help for stripping Keychain support to make mount_smbfs compilable. - WBR, Alexey Proskuryakov _______________________________________________ Do not post admin requests to the list.

I am also not an expert here, but the usual argument against suspending threads is that it's next to impossible to do anything in the remaining thread without risking a dead-lock when waiting for some resource owned by a suspended thread. For example, if some suspended thread happened to be inside a malloc, then any garbage collection would probably block forever. OTOH, if Microsoft did it, it probably works in some cases :) We had the advantage of doing this in an environment -- the VM at the core of .NET -- where we managed all of our threads and knew exactly when it was safe to suspend or resume them. There aren't many scenarios in which that's possible. This email sent to site_archiver(a)lists.apple.com

This bundle is loaded from a CFM host application (using CFBundleCreate and CFBundleLoadExecutable). This seems to work on my machine, as I have a full qt installation. But I would like to embed the qt library and Cg framework inside my bundle, as you would for a standalone application. I have tried using install_name_tool, as is required for a standalone app, but this does not seem to help. On another user's machine, the bundle cannot be loaded. Are there any special steps required to create a self-standing bundle in this way? This email sent to site_archiver(a)lists.apple.com

You can probably get the lists of threads, but the suspension of a related thread in the same process is not supported. That wraps up this mail thread. When I worked for Microsoft we needed to do something similar as part of the shared source CLI. You can download the source code at <http://msdn.microsoft.com/net/sscli/> if you want, but the quick summary is that you can use the Mach thread_suspend and thread_resume functions to do this. To get a Mach thread ID from a pthread, call pthread_mach_thread_np. Technically this isn't supported (as is true for most of the Mach functions), but it's worked fine on every Mac OS X release I've used and I imagine it's likely to continue to work.

As I have just a little time on my hand, I'd like to add the following musings for posterity :) There appear to be some pthread extensions (sorry I lost the links), which go in the direction I need, but they wouldn't work either, since you can't truely nest the suspension calls. To get my scenario to work, it would have to be necessary to be able to suspend and resume a thread multiple times (using a counter). I would have to suspend a thread, that already might be suspended, because I can't be sure, this thread wouldn't unsuspend itself - maybe acquiring a kernel resource -, while I want to do work behind its back. Obviously real-time threads would be cranky, if I suspended them, but that's OK, for in my code, I don't have to worry about and deal with thread priorities.
