\deprecated Use ex_get_set_param()(exoid, EX_NODE_SET, node_set_id, num_nodes_in_set, num_df_in_set)

The function ex_get_node_set_param() reads the number of nodes which
describe a single node set and the number of distribution factors for
the node set.

\return In case of an error, ex_get_node_set_param() returns a
negative number; a warning will return a positive number. Possible
causes of errors include:
  -  data file not properly opened with call to ex_create() or ex_open()
  -  a warning value is returned if no node sets are stored in the file.
  -  incorrect node set ID.

\param[in]  exoid            exodus file ID returned from a previous call to ex_create() or ex_open().
\param[in]  node_set_id      The node set ID.
\param[out] num_nodes_in_set Returned number of nodes in the node set.
\param[out] num_df_in_set    Returned number of distribution factors in the node set.

The following code segment will read a node set from an open exodus
file :
\code
int error, exoid, id, num_nodes_in_set, num_df_in_set, *node_list;
float *dist_fact;

\comment{read node set parameters}
id = 100;

error = ex_get_node_set_param(exoid, id, &num_nodes_in_set, 
                              &num_df_in_set);

\comment{read node set node list}
node_list = (int *) calloc(num_nodes_in_set, sizeof(int));
error = ex_get_node_set(exoid, id, node_list);

\comment{read node set distribution factors}
if (num_df_in_set > 0) {
   dist_fact = (float *) calloc(num_nodes_in_set, sizeof(float));
   error = ex_get_node_set_dist_fact(exoid, id, dist_fact); 
}

\comment{Same result using non-deprecated functions}
error = ex_get_set_param(exoid, EX_NODE_SET, id, &num_nodes_in_set, &num_df_in_set);
error = ex_get_set(exoid, EX_NODE_SET, id, node_list);
if (num_df_in_set > 0) {
   error = ex_get_set_dist_fact(exoid, EX_NODE_SET, id, dist_fact); 
}
