Przemek,
Thank you so much for your explanation. Excellent!
I now have one C function working, so I am on the way! :-)
I now need to use another thread for timing / sampling loop - I have
made a test like this:-
/* ttest.prg */
func main
PUBLIC SampleCsecs:=1, ShutDown:=.F.
//Start Thread 2 to handle sampling and clock
oThread:=Thread():New()
oThread:setInterval( SampleCsecs )
oThread:start( {|| MainClock() } )
DO WHILE !ShutDown
inkey(0)
IF LASTKEY()=27
ShutDown=.T.
EXIT
ENDDO
RETURN
FUNCTION MainClock
DispOutAt(0, MaxCol()-7, Time())
/*Lots of menu and control functions in here*/
IF Shutdown
ThreadObject():setInterval( NIL )
RETURN nil
ENDIF
RETURN nil
---------------end-----------------
It builds without errors but thread 2 never calls MainClock().
I did this in xHarbour with BackgroundTaskAdd (IIRC) and in xBase++ as
above,
what would be the correct approach in Harbour?
I can find no documentation on threads / background tasks and searches
of SVN
have not found anything to help.
Regards, Barry

For each function you want to call from external library you have to
create Harbour function as wrapper to the external C function.
