Difficulties calling function on Complex struct types such as lua_State

[jerishC]

Hi, I want to get more informations from debug value such as lua_State in Lua5.3.lib.

Following this demo, It is possibe to get the lua_State* address and following fixed size memory(BY DkmProcess::ReadMemory). But lua_State is very complicated, and is not easy to copy.

More seriously I can not call any functions from lua_State with the address because it is from another Process. As I Known,there is an old way in natvis called "LegacyAddin" which can make my debug dll and the target project run in the same peocess. But this way isn`t valid after vs 2019.

//complicated struct, there are a lot of pointers
struct lua_State {
  CommonHeader;
  lu_byte status;
  lu_byte allowhook;
  unsigned short nci;  /* number of items in 'ci' list */
  StkId top;  /* first free slot in the stack */
  global_State *l_G;
  CallInfo *ci;  /* call info for current function */
  const Instruction *oldpc;  /* last pc traced */
  StkId stack_last;  /* last free slot in the stack */
  StkId stack;  /* stack base */
  UpVal *openupval;  /* list of open upvalues in this stack */
  GCObject *gclist;
  struct lua_State *twups;  /* list of threads with open upvalues */
  struct lua_longjmp *errorJmp;  /* current error recover point */
  CallInfo base_ci;  /* CallInfo for first level (C calling Lua) */
  volatile lua_Hook hook;
  ptrdiff_t errfunc;  /* current error handling function (stack index) */
  l_uint32 nCcalls;  /* number of allowed nested C calls - 'nci' */
  int stacksize;
  int basehookcount;
  int hookcount;
  volatile l_signalT hookmask;
};

 HRESULT STDMETHODCALLTYPE CLuaStateVisualizerService::EvaluateVisualizedExpression(
    _In_ Evaluation::DkmVisualizedExpression* pVisualizedExpression,
    _Deref_out_opt_ Evaluation::DkmEvaluationResult** ppResultObject
)
{
    HRESULT hr;
    Evaluation::DkmPointerValueHome* pPointerValueHome = Evaluation::DkmPointerValueHome::TryCast(pVisualizedExpression->ValueHome());
    if (pPointerValueHome == nullptr)
    {
        return E_NOTIMPL;
    }

    DkmRootVisualizedExpression* pRootVisualizedExpression = DkmRootVisualizedExpression::TryCast(pVisualizedExpression);
    if (pRootVisualizedExpression == nullptr)
    {
        return E_NOTIMPL;
    }
    // I can get the lua_State address, but 
    DkmProcess* pTargetProcess = pVisualizedExpression->RuntimeInstance()->Process();
    lua_State* value = (lua_State*)pPointerValueHome->Address();
    int n = lua_gettop(L);//Crashed , read access violation. beacuse read address from another process 

Could give me any suggestions? Thanks
