This function returns true (1) or false (0)
depending on whether the device that you specify is being used or
not. Now, the device refers to the mouse number, which can
be from 0 to 4 and this event is triggered when the touch screen of
a mobile device is touched, so in this way you can test for up to
n different screen touches (the maximum number of touches
that can be detected will depend very much on the device being used
and the OS it runs). This function constantly updates every step,
and the standard constants of mb_left and
mb_right can be used to check for either button.
