SysHandleEvent is a switch-case statement internally right? at least,
it better be :P if it is a switch-case, it'll not be worth calling
EvtEventAvail() :)
--------------------------------
More something like:
if (xxx1)
yyy1;
if (xxx2)
yyy2;
if (event == nilEvent)
zzz; // Not really useful actually - I can't say much
switch (event)
{
}
I still think it's worth not to call it if you know there is no reason.
--------------------------------
but, depends on how palm has written it of course :P i aint checked
this recently - maybe i should *g*. Daniel Morais has also posted a
few hints here on how to disable stylus processing etc which will also
give you a bit more CPU grunt for your money :P
