Unless you're writing code for OS 9 (which you probably shouldn't be
doing), OT shouldn't be used. Look into using sockets or CFNetwork
instead.

Hi, I need a way to run a cooperative thread or callback at system
task time. I have a network class that needs to run even if a dialog
box is showing. My code is not interrupt safe, it is an Idle()
function that polls for UDP packets and handles keepalives/timeouts,
that I normally call during my main loop. I tried creating a
cooperative thread with NewThread() that just sits in a loop and
beeps then yields every second, but unfortunately it only runs if I
call YieldToAnyThread(). Dialog boxes evidently don't call the
thread manager! That is a pretty bad mistake in the Mac OS haha. I
guess that stuff is deprecated so there should be a modern routine
that creates a cooperative thread that gets called during dialogs, or
in WaitNextEvent() or RunApplicationEventLoop() etc.
I really don't want to get into preemptive threads and mutexes around
WNE or my network class, just to emulate a simple cooperative
thread. I can maybe patch SystemTask() if that is still possible.
Really, I need OTCreateSystemTask() or something with identical
functionality. I can't install an event filter because the
networking needs to always run even if a system dialog is showing.
Thanx,
