Pointer Driver Function Definitions
F_ISR (AH
=
OOH)
This function receives an ISR Event record from one of the physical GID drivers. The calling driver
has handled the physical interrupt and updated the Physical Describe Record to reflect the event.
This function translates the physical event into the logical coordinate system and calls its parent,
V_EVENT_POINTER, (if EVENT is enabled). In addition, this function passes the event to
V_STRACK so that the sprite can be updated (if TRACK is enabled). This function is a response
to a logical hardware interrupt and not user callable.
