_map_segment.mask_array_id

Definition:

   
    The value of _map_segment.mask_array_id, if given, the array
    structure into which the mask for the map is organized.  If no
    value is given, then all elements of the map are valid.  If a
    value is given, then only elements of the map for which the
    corresponding element of the mask is non-zero are valid.  The
    value of _map_segment.mask_array_id differs from the value of
    _map_segment.array_id in order to permit the mask to be given
    as, say, unsigned 8-bit integers, while the map is given as
    a data type with more range.  However, the two array structures
    must be aligned, using the same axes in the same order with the
    same displacements and increments
    This item is a pointer to _array_structure.id in the
    ARRAY_STRUCTURE category.
