  [in, out]                                    HCORENUM  *phEnum,
  [out, size_is(cMax), length_is(*pcTypeDefs)] mdTypeDef rgTypeDefs[],
  [in]                                         ULONG     cMax,
  [out, retval]                                ULONG     *pcTypeDefs
);

Parameters

phEnum [in, out]: A pointer to the new enumerator. This must be NULL for the first call of this method.
rgTypeDefs [out]: The array used to store the TypeDef tokens.
