int user_init_draw_graph(void *user, int dg_id)
This function is invoked only if the do_draw_graph parameter is set. The user can initialize the graph drawing process by sending some initial information (e.g., the location of the nodes of a graph, like in the TSP.)
void *user | IN | Pointer to the user-defined data structure. |
int dg_id | IN | The process id of the graph drawing process. |
ERROR | Error. SYMPHONY stops. |
USER_NO_PP | The user completed initialization successfully. |
