[linux-audio-dev] gettimeofday() realtime safe?

Hi all, I need to know if gettimeofday (or one of the other standard time functions) is okay to use in a realtime jack thread. I can't find any information on the net about whether it's deterministic or not (or even how expensive it is). Problem is I have an event-based system that pushes events (from OSC/Midi) into a dequeue, which the audio thread runs through to execute. If you flood with events, too many need to be processed per block, the audio thread takes too long and you get dropouts. I'd like to be able to only process (non timestamped) events for x% of the time available to prevent this from happening; so I need to be able to determine how much time has been eaten by event processing so far. Is calling gettimeofday this many times in the realtime thread a wise idea? Cheers, -DR-
