VDD_IO_HANDLERS defines an array of handlers for the VDD I/O hooks.

Members

inb_handler

A pointer to the VDD-provided function to simulate INB instruction. This handler is mandatory.

inw_handler

A pointer to the VDD-provided function to simulate INW instruction. This handler is optional; the system will simulate this function by using the provided INB handler.

insb_handler

A pointer to the VDD-provided function to simulate INSB instruction. This handler is optional; the system will simulate this function by using the provided INB handler.

insw_handler

A pointer to the VDD-provided function to simulate INSW instruction. This handler is optional; the system will simulate this function by using the provided INB handler.

outb_handler

A pointer to the VDD-provided function to simulate OUTB instruction. This handler is mandatory.

outw_handler

A pointer to the VDD-provided function to simulate OUTW instruction. This handler is optional; the system will simulate this function by using the provided OUTB handler.

outsb_handler

A pointer to the VDD-provided function to simulate OUTSB instruction. This handler is optional; the system will simulate this function by using the provided OUTB handler.

outsw_handler

A pointer to the VDD-provided function to simulate OUTSW instruction. This handler is optional; the system will simulate this function by using the provided OUTB handler.
