Can TThread.Synchronize() be used in a non-graphical program (i.e.

Synchronize relies on checksynchronize being called regularly from the
main thread.
If you use readln() or so, then it's not useful.
Thanks, I'm reading stdin directly with a tight timeout using fpselect
so it sounds like I should be able to manage something.
There is also the event Classes.WakeMainThread (of type TNotifyEvent)
which is executed if a thread calls Synchronize (and "Queue" in 2.7.1).
This event can be used to trigger the execution of CheckSynchronize.
Please note that WakeMainThread is executed in context of the calling
thread while CheckSynchronize *must* be called from the main thread.
Since you are using fpselect you could use a pipe which is filled by
WakeMainThread and wait on that as well.

Sven
