REMARKS:
Data structure containing ponters to programmed I/O functions used by the
emulator. This is used so that the user program can hook all programmed
I/O for the emulator to handled as necessary by the user program. By
default the emulator contains simple functions that do not do access the
hardware in any way. To allow the emualtor access the hardware, you will
need to override the programmed I/O functions using the X86EMU_setupPioFuncs
function.

REMARKS:
Data structure containing ponters to memory access functions used by the
emulator. This is used so that the user program can hook all memory
access functions as necessary for the emulator. By default the emulator
contains simple functions that only access the internal memory of the
emulator. If you need specialised functions to handle access to different
types of memory (ie: hardware framebuffer accesses and BIOS memory access
etc), you will need to override this using the X86EMU_setupMemFuncs
function.
