[Jack-Devel] Non-blocking I/O in process callback

Hello, I'm wondering whether it's safe to do non-blocking reads or writes from inside the process callback. From what I've seen, non-blocking I/O doesn't cause the process to go into blocked state, and the realtime scheduler should not switch to another process. But the documentation doesn't seem to allow them: So, is it safe to use non-blocking I/O in the process callback? Thank you, Xavi
