The following code snippet illustrates the use of CreateNewState.

  
// Declare local identifiers:
HRESULT                       hr = S_OK;
CComPtr<ISpGrammarBuilder>    cpGrammarBuilder;
SPSTATEHANDLE                 hInit;
SPSTATEHANDLE                 hState;
SPSTATEHANDLE                 hState2;

hr = cpGrammarBuilder->GetRule(L"rule1", 1, 0, TRUE, &hInit;);

if (SUCCEEDED (hr))
{
   // Call CreateNewState using the initial state.
hr = cpGrammarBuilder->CreateNewState(hInit, &hState;);
}

if (SUCCEEDED (hr))
{
   // Call CreateNewState using hState != hInit.
   hr = cpGrammarBuilder->CreateNewState(hState, &hState2;);
}

if (SUCCEEDED(hr))
{
   // Do something here.
