Creates a type definition for a common language runtime type, and gets a metadata token for that type definition.
HRESULT DefineTypeDef ( [in] LPCWSTR szTypeDef, [in] DWORD dwTypeDefFlags, [in] mdToken tkExtends, [in] mdToken rtkImplements, [out] mdTypeDef *ptd );
[in] The name of the type in Unicode.
TypeDef attributes. This is a bitmask of
[in] The token of the base class. It must be either an
mdTypeDef or an
[in] An array of tokens specifying the interfaces that this class or interface implements.
mdTypeDef token assigned.
A flag in
dwTypeDefFlags specifies whether the type being created is a common type system reference type (class or interface) or a common type system value type.
Depending on the parameters supplied, this method, as a side effect, may also create an
mdInterfaceImpl record for each interface that is inherited or implemented by this type. However, this method does not return any of these
mdInterfaceImpl tokens. If a client wants to later add or modify an
mdInterfaceImpl token, it must use the
IMetaDataImport interface to enumerate them. If you want to use COM semantics of the
[default] interface, you should supply the default interface as the first element in
rtkImplements; a custom attribute set on the class will indicate that the class has a default interface (which is always assumed to be the first
mdInterfaceImpl token declared for the class).
Each element of the
rtkImplements array holds an
mdTypeRef token. The last element in the array must be
