Note: The 'dwSize' member of a structure X must be set to sizeof(X)
before calling the associated API, otherwise ERROR_INVALID_SIZE is
returned. The APIs determine the size using 2-byte packing (the
default for Microsoft compilers when no /Zp<n> option is supplied).
Users requiring non-default packing can use the 'dwSize' values
listed next to each 'dwSize' member in place of sizeof(X). }
