IMetaDataDispenser::DefineScope Method

Creates a new area in memory in which you can create new metadata.

HRESULT DefineScope (
    [in]  REFCLSID    rclsid,
    [in]  DWORD       dwCreateFlags,
    [in]  REFIID      riid, 
    [out] IUnknown    **ppIUnk
);

rclsid

[in] The CLSID of the version of metadata structures to be created. This value must be CLSID_CorMetaDataRuntime for the .NET Framework version 2.0.

dwCreateFlags

[in] Flags that specify options. This value must be zero for the .NET Framework 2.0.

riid

[in] The IID of the desired metadata interface to be returned; the caller will use the interface to create the new metadata.

The value of riid must specify one of the "emit" interfaces. Valid values are IID_IMetaDataEmit, IID_IMetaDataAssemblyEmit, or IID_IMetaDataEmit2.

ppIUnk

[out] The pointer to the returned interface.

DefineScope creates a set of in-memory metadata tables, generates a unique GUID (module version identifier, or MVID) for the metadata, and creates an entry in the module table for the compilation unit being emitted.

You can attach attributes to the metadata scope as a whole by using the IMetaDataEmit::SetModuleProps or IMetaDataEmit::DefineCustomAttribute method, as appropriate.
