Why doesn’t OS X support POSIX.1b? No, really?
I’m working on writing a threadsafe compiler as part of my research project this summer. The RTS extensions allow you to send an integer or pointer along with a signal (via the sigqueue function). Unfortunately, sigqueue and much of RTS is missing from OS X Leopard, as it’s an optional part of the SUS / UNIX 03 spec.
The really odd thing is that it implements enough of POSIX.1b to receive integers/pointers from a sending process, but not enough to send them. WTF?
Any thoughts on portably sending an integer value between process in a high-performance way? Pipes just don’t seem as clean as a sigqueue call…
