how to make debug tools like Windbg or Sice?

here ,with win2k leak code,we can make more powerful debug tool with
easy way..
hm,,,even more power than olly and sice..
let's to the point..
first, u must have ddk and win2k leak code

here, win2k leak code is placed in f:\win2k
so,setenv after enter ddk setenv command:
set BASEDIR=F:\win2k
set MFC_LIBDIR=D:\NTDDK\lib\mfc
set SDK_LIB_PATH=D:\NTDDK\lib
set CRT_INC_PATH=
set VCTOOLS=F:\win2k\private\windbg64
1.link base lib
enter f:\win2k\win2k\private\windbg64\debugger\memlist
build

enter
F:\win2k\win2k\private\windbg64\debugger\od
build
all above is basic abstract debug api

2.build main app
enter
F:\win2k\win2k\private\windbg64\debugger\tl\remote\gambit\shell
build
notes that tlloc.dll ,em.dll are copied into these dirtory.
becauze lacked some headers, these .dll cannot be compiled

ps:em.dll and dm.dll are api that's abstact funcs call such as
unassemble,break point....u can look insight via code

anyway,the follow is how to use these API:
OSDInit(&Dbf);
HModTL = LoadLibrary("tlloc.dll");
GetProcAddress(HModTL, "TLFunc");
HModEM = LoadLibrary("em.dll");
GetProcAddress(HModEM, "EMFunc");
OSDCreateHpid(OSDCallbackFunc, Hem, Htl, &HpidBase);
OSDProgramLoad(HpidBase,"test.exe",NULL,NULL,"DBG:",ulfMultiProcess);
....
OSDGo(HpidBase, HtidBase, &exop);
OSDSingleStep(HpidBase, HtidBase, &exop);
OSDUnassemble(HpidBase,HtidBase,&sdi);
...

yep,any debug api is enveloped in ODNT.LIB
and u can easy use these OSDXXX api to debug u code
to do more sophicated thing, such as output call-times,
"mov" times,jmp times......

so,next time...
i will expand u how to uncompile file,not unassemble.

attached is easy frame,u can change it to more complex style...
