     Purpose
    kusano 7d535a
     =======
    kusano 7d535a
        ssnode_dfs() - Determine the union of the row structures of those 
    kusano 7d535a
        columns within the relaxed snode.
    kusano 7d535a
        Note: The relaxed snodes are leaves of the supernodal etree, therefore, 
    kusano 7d535a
        the portion outside the rectangular supernode must be zero.

    kusano 7d535a
     Return value
    kusano 7d535a
     ============
    kusano 7d535a
         0   success;
    kusano 7d535a
        >0   number of bytes allocated when run out of memory.
