49 * 32-bit segmented (DPMI32) and 32-bit linear (via DeviceIoControl).
50 * For automatic conversion of pointer
51 * parameters, interrupt handlers should use CTX_SEG_OFF_TO_LIN with
52 * the contents of a segment register as second and the contents of
53 * a *32-bit* general register as third parameter, e.g.
54 * CTX_SEG_OFF_TO_LIN( context, DS_reg(context), EDX_reg(context) )
55 * This will generate a linear pointer in all three cases:
56 * Real-Mode: Seg*16 + LOWORD(Offset)
57 * 16-bit: convert (Seg, LOWORD(Offset)) to linear
58 * 32-bit segmented: convert (Seg, Offset) to linear
59 * 32-bit linear: use Offset as linear address (DeviceIoControl!)
61 * Real-mode is recognized by checking the V86 bit in the flags register,
62 * 32-bit linear mode is recognized by checking whether 'seg' is
63 * a system selector (0 counts also as 32-bit segment) and 32-bit
64 * segmented mode is recognized by checking whether 'seg' is 32-bit
65 * selector which is neither system selector nor zero.
