To clone a complete layout with properties and entities…

void createClone()
{
  Acad::ErrorStatus es;   
  AcDbDatabase *curDocDB =acdbHostApplicationServices()->workingDatabase();   
  AcApLayoutManager *layoutMngr =
(AcApLayoutManager*)(acdbHostApplicationServices()->layoutManager());      
  curDocDB->setTilemode(Adesk::kFalse);   
  const ACHAR *actLayoutName = layoutMngr->findActiveTab();      
  //no layout objects may be open kForWrite during getNextNewLayoutName()   
  ACHAR *cloneName = layoutMngr->getNextNewLayoutName();   
  AcDbLayout *pSrc = layoutMngr->findLayoutNamed(actLayoutName, TRUE);   
  if (pSrc == NULL)
  {      
   acutDelString(cloneName);      
   return;   
  }   
  es = layoutMngr->cloneLayout(pSrc, cloneName);   
  acutDelString(cloneName);   
  pSrc->close();   
  if (es == Acad::eOk)      
   layoutMngr->updateLayoutTabs();
