Are you trying to develop for Mac OS X or Mac OS 9?
For Mac OS X, you should seriously consider switching to a CFRunLoop
and using sockets and CFSocket to handle networking.
NewThread, OTCreateSystemTask, WaitNextEvent, SystemTask are all a
compatibility shim to keep old code limping along. They are not
intended for new code development.

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,
