## Function Documentation

## ◆ ex_put_elem_attr()

int ex_put_elem_attr | ( | int | exoid,
|  | ex_entity_id | elem_blk_id,
|  | const void * | attrib
| ) |  |

Deprecated:
  Use ex_put_attr()(exoid, EX_ELEM_BLOCK, elem_blk_id, attrib)

The function ex_put_elem_attr() writes the attributes for an element block. Each element in the element block must have the same number of attributes, so there are(num_attr x num_elem_this_blk) attributes for each element block. The function ex_put_elem_block() must be invoked before this call is made.

Because the attributes are floating point values, the application code must declare the array passed to be the appropriate type (float or double) to match the compute word size passed in ex_create() or ex_open().

Returns
  In case of an error, ex_put_elem_attr() 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()
  - data file opened for read only.
  - data file not initialized properly with call to ex_put_init().
  - ex_put_elem_block() was not called previously for specified element block ID.
  - ex_put_elem_block() was called with 0 attributes specified.

Parameters

  [in] | exoid | exodus file ID returned from a previous call to ex_create() or ex_open().
  [in] | elem_blk_id | The element block ID.
  [in] | attrib | Size [num_elem_this_blk*num_attr] The list of attributes for the element block. The num_attr index cycles faster.

Refer to the code example in ex_put_elem_block() for an example of writing the attributes array for an element block.
