Suck it and see; if the resolution of the machine is significantly greater
than the incoming events, all should be well and good.
Cheers.
A flag implies a line of code that says
//No, flag should be getting the number of events var flag:integer;
xxxxx.onevent(blabla)
begin
flag:=flag+1;
if flag>1 then exit;
while flag >0 do
// now, unless my understanding of reentrant pascal is err, if an onevent
occurs here the loop breaks & does the onevent,
//incs flag, exits, then continues in this loop where it was exited
begin
flag := flag-1;
// do stuff
end;
end;
intialization flag:=0;
The concern is as to whether it is possible for two instances to exit
the loop before one of them has set the flag to true?
