My understanding is that these functions are only optionally implemented in
any given Palm OS implemention. But I use 'em:
struct ScreenLocker {
ScreenLocker(WinLockInitType initMode = winLockCopy) :
_ret(WinScreenLock(initMode))
{
}
~ScreenLocker() { if (_ret) WinScreenUnlock(); }
private:
UInt8* _ret;
};
Example:
void SomeDrawFunc()
{
ScreenLocker locker;
// draw stuff
}
