Thread safety of CGEventSourceFlagsState()

  • Subject: Thread safety of CGEventSourceFlagsState()

Even after reading last week's discussion I'm still not sure if it is OK to get the current modifier keys from a secondary thread.  I realize that the keyboard is not a GUI, but it's UI, and I'm worried about that "accessing GUI from secondary thread" thing.

Is it OK to call CGEventSourceFlagsState() from a secondary thread?

Data Point: I tried it and it didn't crash.

Thanks,

Jerry Krinock
