## Function Documentation

## ssnode_dfs()

int_t ssnode_dfs | ( | const int | jcol,
|  | const int | kcol,
|  | const int_t * | asub,
|  | const int_t * | xa_begin,
|  | const int_t * | xa_end,
|  | int_t * | xprune,
|  | int * | marker,
|  | GlobalLU_t * | Glu
| ) |  |

    Purpose
    =======
       ssnode_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.
