Int 2F Fn 4310  - Cloaking - Real-mode Api                                 [m]

   AX = 4310h

Return: ES:BX -> driver entry point (see #2436,#2465,#2466,#2467,#2468)

(Table 2465)
Call the Cloaking v1.01 "Client Registration" function with:
   AH = 7Eh
   BX = subfunction
       0000h get client registration count
       0001h get client registration structures
       ES:DI -> buffer for registration structures

Return: AX = status
       0000h failed
       0001h successful
       ---subfunction 00h---
       BX = size of client structure in bytes
       CX = number of clients installed
       ---subfunction 01h---
       ES:DI buffer filled

(Table 2466)
Call the Cloaking v1.01 "Verify Cloaking Host" function with:
   AH = 7Fh

Return: AX = status
       0000h failed
       0001h (successful) if installed
       BX = version (0101h for v1.01)
       CX = flags
           bit 0: host is VCPI-based
       DS:DX -> ASCIZ Cloaking host signature
           "CLOAKING.EXE"0, followed by a far-call entry point to
             uninstall host (see #2467) in Helix's CLOAKING.EXE

(Table 2467)
Call the CLOAKING.EXE "Uninstall Host" function with:

Return: AX = 4F4Bh ('OK') if successfully uninstalled protected-mode code

(Table 2468)
Call the Cloaking "Start Protected-Mode Client" function with:
   AH = 82h
   DX = XMS handle of locked block containing protected-mode code
   CL = code size (00h 16-bit, else 32-bit)
   ESI, EDI = parameters to pass to protected-mode code

Return: AX = status
       nonzero success
       0000h failed
       BL = error code (A2h,B0h) (see #2462)

Notes: this function calls a user initialization function at offset 0 in
     the XMS memory block (see #2469)
   supported by Helix's RM386 v6.00 and Helix's CLOAKING.EXE

See Also: #2465,#2466

(Table 2469)
Values user initialization function is called with:
   EBX = physical address of block's start
   ESI = user data from function 82h call
   EDI = user data from function 82h call
   CS = code selector for XMS block at EBX (16-bit or 32-bit)
   DS = data selector for XMS block, starting at EBX
   ES = selector for V86 memory access to full real-mode 1088K
   GS = selector for full 4G flat address space
   SS:ESP -> stack provided by host

Return: via 32-bit FAR return

Note:  the initialization function may call any protected-mode Cloaking
     service; it should store the values of DS, ES, and GS for future
     reference
