Purpose
ilu_zsnode_dfs() - Determine the union of the row structures of those columns within the relaxed snode. Note: The relaxed snodes are leaves of the supernodal etree, therefore, the portion outside the rectangular supernode must be zero.
Return value
0 success; >0 number of bytes allocated when run out of memory.
