Load debug symbols from a data stream given the ICorDebugModule object.

Syntax

HRESULT LoadSymbolsFromStreamWithCorModule(
    ULONG32   ulAppDomainID,
    GUID      guidModule,
    ULONGLONG baseAddress,
    IUnknown* pUnkMetadataImport,
    IUnknown* pUnkCorDebugModule,
    IStream*  pStream
);

int LoadSymbolsFromStreamWithCorModule(
    uint    ulAppDomainID,
    Guid    guidModule,
    ulong   baseAddress,
    object  pUnkMetadataImport,
    object  pUnkCorDebugModule,
    IStream pStream
);

Parameters

ulAppDomainID
[in] Identifier of the application domain.

guidModule
[in] Unique identifier of the module.

baseAddress
[in] Base memory address.

pUnkMetadataImport
[in] Object that contains the symbol metadata.

pUnkCorDebugModule
[in] Object that implements the ICorDebugModule Interface.

pStream
[in] Data stream that contains the debug symbols to load.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

Example

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

HRESULT CDebugSymbolProvider::LoadSymbolsFromStreamWithCorModule(
    ULONG32 ulAppDomainID,
    GUID guidModule,
    ULONGLONG baseOffset,
    IUnknown* pUnkMetadataImport,
    IUnknown* pUnkCorDebugModule,
    IStream* pStream
)
{
    CAutoLock Lock(this);

    HRESULT hr = S_OK;
    CComPtr<IMetaDataImport> pMetadata;
    CComPtr<ICorDebugModule> pCorModule;

    CModule* pmodule = NULL;
    CModule* pmoduleNew = NULL;
    bool fAlreadyLoaded = false;
    Module_ID idModule(ulAppDomainID, guidModule);
    DWORD dwCurrentState = 0;

    ASSERT(IsValidObjectPtr(this, CDebugSymbolProvider));
    ASSERT(IsValidInterfacePtr(pUnkMetadataImport, IUnknown));

    METHOD_ENTRY( CDebugSymbolProvider::LoadSymbolsFromStream );

    IfFalseGo( pUnkMetadataImport, E_INVALIDARG );
    IfFalseGo( pUnkCorDebugModule, E_INVALIDARG );

    IfFailGo( pUnkMetadataImport->QueryInterface( IID_IMetaDataImport,
              (void**)&pMetadata) );

    IfFailGo( pUnkCorDebugModule->QueryInterface( IID_ICorDebugModule,
              (void**)&pCorModule) );

    ASSERT(guidModule != GUID_NULL);

    fAlreadyLoaded = GetModule( idModule, &pmodule ) == S_OK;

    IfNullGo( pmoduleNew = new CModule, E_OUTOFMEMORY );

    dwCurrentState = m_pSymProvGroup ? m_pSymProvGroup->GetCurrentState() : 0;

    IfFailGo( pmoduleNew->Create( idModule,
                                  dwCurrentState,
                                  pMetadata,
                                  pCorModule,
                                  pStream,
                                  baseOffset ) );

    if (fAlreadyLoaded)
    {
        IfFailGo(pmoduleNew->AddEquivalentModulesFrom(pmodule));
        RemoveModule(pmodule);
    }

    IfFailGo( AddModule( pmoduleNew ) );

Error:

    RELEASE (pmodule);
    RELEASE (pmoduleNew);

    METHOD_EXIT( CDebugSymbolProvider::LoadSymbolsFromStream, hr );

    return hr;
}
