Purpose
=======
<a class="el" href="csnode__dfs_8c.html#ab788afd5e122cb5d92ff4d78dace7854">csnode_dfs()</a> - 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.
