Int 2F/AX=4310h

Cloaking - REAL-MODE API

AX = 4310h

Return:
ES:BX -> driver entry point (see #02749,#02778,#02779,#02780,#02781)

See Also: AX=4310h"XMS"



(Table 02778)
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 02779)
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 #02780) in Helix's CLOAKING.EXE

(Table 02780)
Call the CLOAKING.EXE "Uninstall Host" function with:

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


(Table 02781)
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 #02775)

Notes: This function calls a user initialization function at offset 0 in the XMS memory block (see #02782). Supported by Helix's RM386 v6.00 and Helix's CLOAKING.EXE

See Also: #02778 - #02779



(Table 02782)
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
