63REMARKS:
64Data structure containing ponters to programmed I/O functions used by the
65emulator. This is used so that the user program can hook all programmed
66I/O for the emulator to handled as necessary by the user program. By
67default the emulator contains simple functions that do not do access the
68hardware in any way. To allow the emualtor access the hardware, you will
69need to override the programmed I/O functions using the X86EMU_setupPioFuncs
70function.

93REMARKS:
94Data structure containing ponters to memory access functions used by the
95emulator. This is used so that the user program can hook all memory
96access functions as necessary for the emulator. By default the emulator
97contains simple functions that only access the internal memory of the
98emulator. If you need specialised functions to handle access to different
99types of memory (ie: hardware framebuffer accesses and BIOS memory access
100etc), you will need to override this using the X86EMU_setupMemFuncs
101function.
