## Function Documentation

## ◆ ex_get_node_set_ids()

int ex_get_node_set_ids | ( | int | exoid,
|  | void_int * | ids
| ) |  |

Deprecated:
  Use ex_get_ids()(exoid, EX_NODE_SET, ids)

The function ex_get_node_set_ids() reads the IDs of all of the node sets. Memory must be allocated for the returned array of ({num_node_sets}) IDs before this function is invoked.

Returns
  In case of an error, ex_get_node_set_ids() 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.

Parameters

  [in] | exoid | exodus file ID returned from a previous call to ex_create() or ex_open().
  [out] | ids | Returned array of the node sets IDs. The order of the IDs in this array reflects the sequence the node sets were introduced into the file.

As an example, the following code will read all of the node set IDs from an open data file:

int *ids, num_node_sets, error, exoid;
/* read node sets IDs */
ids = (int *) calloc(num_node_sets, sizeof(int));
error = ex_get_node_set_ids (exoid, ids);
/* Same result using non-deprecated functions. */
error = ex_get_ids (exoid, EX_NODE_SET, ids);
