IDebugComPlusSymbolProvider::IsHiddenCode

  • Artikkeli

Determines if the code at the specified debugger address is hidden.

Syntax

int IsHiddenCode(
    IDebugAddress pAddress
);

Parameters

pAddress
[in] The debug address that is represented by an IDebugAddress interface.

Return Value

If the code is hidden, returns S_OK; otherwise, returns S_FALSE.

Example

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

HRESULT CDebugSymbolProvider::IsHiddenCode(
    IDebugAddress* pAddress
)
{
    HRESULT hr = S_OK;
    CDEBUG_ADDRESS address;
    CComPtr<CModule> pModule;

    ASSERT(IsValidObjectPtr(this, CDebugSymbolProvider));
    ASSERT(IsValidInterfacePtr(pAddress, IDebugAddress));

    METHOD_ENTRY( CDebugSymbolProvider::IsHiddenCode );

    IfFalseGo( pAddress, S_FALSE );
    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->IsHiddenCode( address.addr.addr.addrMethod.tokMethod,
                                address.addr.addr.addrMethod.dwVersion,
                                address.addr.addr.addrMethod.dwOffset ))
    {

        // S_FALSE indicates this sequence point is not hidden

        hr = S_FALSE;
    }

Error:

    METHOD_EXIT( CDebugSymbolProvider::IsHiddenCode, hr );

    if (!SUCCEEDED(hr))
    {
        hr = S_FALSE;
    }

    return hr;
}
