Example

The following example shows how to implement this method for a CDebugGenericParamFieldType object that exposes the IDebugGenericParamField interface.

HRESULT CDebugGenericParamFieldType::GetIndex(DWORD* pIndex)
{
    HRESULT hr = S_OK;

    METHOD_ENTRY( CDebugGenericParamFieldType::GetIndex );

    IfFalseGo(pIndex, E_INVALIDARG );
    IfFailGo( this->LoadProps() );
    *pIndex = m_index;

Error:

    METHOD_EXIT( CDebugGenericParamFieldType::GetIndex, hr );
    return hr;
}
