Syntax

C#

int UnloadSymbols(
    uint ulAppDomainID,
    Guid guidModule
);

C++

HRESULT UnloadSymbols(
    ULONG32 ulAppDomainID,
    GUID    guidModule
);

Parameters

ulAppDomainID
[in] Identifier of the application domain.

guidModule
[in] Unique identifier of the module.

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 IDebugComPlusSymbolProvider interface.

HRESULT CDebugSymbolProvider::UnloadSymbols(
    ULONG32 ulAppDomainID,
    GUID guidModule
)
{
    HRESULT hr = S_OK;
    CComPtr<CModule> pmodule;
    Module_ID idModule(ulAppDomainID, guidModule);

    METHOD_ENTRY( CDebugSymbolProvider::UnloadSymbols );

#if DEBUG

    DebugVerifyModules();
#endif

    IfFailGo( GetModule( idModule, &pmodule ) );

#if DEBUG

    DebugVerifyModules();
#endif

    RemoveModule( pmodule );
    pmodule->Cleanup();

Error:
#if DEBUG

    DebugVerifyModules();
#endif

    METHOD_EXIT( CDebugSymbolProvider::UnloadSymbols, hr );

    return hr;
}
