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

Hi Xavi, If the time to complete the function is deterministic, it is real time safe. System calls (blocking ones) have "unbounded execution time", and as such are not rt safe. If your I/O will take a significant amount of time, I suggest offloading to a worker thread.

But the documentation doesn't seem to allow them: So, is it safe to use non-blocking I/O in the process callback?
