I posted this earlier, but for some reason it didn't seem to get posted:
-----------------
I've noticed this when you do a hard reset. The "Erase all data? YES - up
button" screen" drives my system to a crawl.
I'm sure it's just a poorly written tight loop in the emulator.
If you write a windows program like this
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
while (true)
NULL;
return 0;
}
All your CPU cycles will be eaten up.
A well written app will not do anything if it has nothing in the queue, like
this
while (GetMessage(&msg, NULL, 0, 0))
{
}
GetMessage doesn't return unless there is a relavent message, so it lets the
system do its thing when the app is idle.
In some cases the emulator appears to just do a tight loop.
--------
Anyway, I did a little testing and discovered i was not quite right anyway.
It's not the emulator, its your program.
If you do a tight loop in a Palm program on the emulator (or otherwise do a
lot of stuff without quitting and letting the Palm OS event handler do its
thing), the emulator will, of course suck up all available CPU cycles. This
is what you would want it to do if you are doing heavy computation. If you
are just idle, don't do an idle loop, just return from your event handler
and wait for the Palm OS to pass you your next event. I'm sure there's a
good technical reason why the Palm OS's "Erase All Data" is doing a loop
that constantly checks for a key down (which sucks up all cpu cycles) rather
than a blocking call (which would do nothing at all until a key down event
was received).
