Determines if the specified debug address is a sequence point.

Syntax

HRESULT IsAddressSequencePoint(  
   IDebugAddress* pAddress  
);  

int IsAddressSequencePoint(  
   IDebugAddress pAddress  
);

Parameters

pAddress
[in] Debug address that is represented by the IDebugAddress interface.

Return Value

If the debug address is a sequence point, returns S_OK; otherwise, returns S_FALSE.

Example

The following example shows how to implement this method for a CDebugSymbolProvider object that exposes the IDebugComPlusSymbolProvider2 interface.

HRESULT CDebugSymbolProvider::IsAddressSequencePoint(  
    IDebugAddress* pAddress  
)  
{  
    HRESULT hr = S_OK;  
    CDEBUG_ADDRESS address;  
    CComPtr<CModule> pModule;  
  
    METHOD_ENTRY( CDebugSymbolProvider::LoadSymbol );  
  
    IfFalseGo( pAddress, E_INVALIDARG );  
  
    IfFailGo( pAddress->GetAddress( &address ) );  
  
    ASSERT(address.addr.dwKind == ADDRESS_KIND_METADATA_METHOD);  
    IfFalseGo( address.addr.dwKind == ADDRESS_KIND_METADATA_METHOD, S_FALSE );  
  
    IfFailGo( GetModule( address.GetModule(), &pModule) );  
  
    if (!pModule->IsSequencePoint( address.addr.addr.addrMethod.tokMethod,  
                                   address.addr.addr.addrMethod.dwVersion,  
                                   address.addr.addr.addrMethod.dwOffset ))  
    {  
  
        // S_FALSE indicates this is not a sequence point  
  
        hr = S_FALSE;  
    }  
  
Error:  
  
    METHOD_EXIT( CDebugSymbolProvider::LoadSymbol, hr );  
  
    return hr;  
}
