If file handlers were thread-specific you would not be able to read files on other threads. They are process-specific, not thread-specific. At its core, select is very much synchronous. This haunted

I don’t think file descriptors are thread specific. Most of your parameters to select are pointers. But what do they point to? If they point to structures on the stack, that would be bad, because

yes of course file handles are thread-specific, you wouldn’t want random bits of code trying 0, 1, 2 … to see what it could get. Actually they are process-specific, but the process running your

I need to do select() with a rather large timeout value (several minutes). So in order not to block the runLoop / mainThread I tried: dispatch_queue_t myQueue = dispatch_get_global_queue(

Hi All, I’m trying to update an old Mac Pro Early 2008 from 10.10.5 to 10.11.6, does anyone know how to do this? I can’t find it on the App Store and can’t find a separate .dmg file to

macOS 13.1 Is there a way to ascertain whether a process is sleeping or awake? There is IORegisterForSystemPower which sends seep/wake notifications but needs a runloop. Anything else? Background:

Shared libraries for talking to iOS devices. Possibly debugger & profiler infrastructure (stuff for getting access to other processes.) Etc. Xcode has been installing this stuff since at least version

I think it’s installing components that allow access to devices. I have no idea what’s modified. No. [1] contains a complete Unix C build environment (tools, headers, libraries) that’s used when

After migrating to macOS 13.1 when I first started Xcode (9.1) it told me that it had to install some components. What are these “components” and where do they live? Also: My macOS 13 partition
