34 * A window an array of __LINE structures pointed to by the 'lines' pointer.
35 * A line is an array of __LDATA structures pointed to by the 'line' pointer.
36 *
37 * IMPORTANT: the __LDATA structure must NOT induce any padding, so if new
38 * fields are added -- padding fields with *constant values* should ensure
39 * that the compiler will not generate any padding when storing an array of
40 * __LDATA structures. This is to enable consistent use of memcmp, and memcpy
41 * for comparing and copying arrays.
