int	ex_get_elem_attr (int exoid, ex_entity_id elem_blk_id, void *attrib)

Function Documentation

ex_get_elem_attr()

int ex_get_elem_attr	(	int	exoid,
		ex_entity_id	elem_blk_id,
		void *	attrib )

Deprecated

Use ex_get_attr()(exoid, EX_ELEM_BLOCK, elem_blk_id, attrib) instead

The function ex_get_elem_attr() reads the attributes for an element block. Memory must be allocated for(num_attr x num_elem_this_blk) attributes before this routine is called.

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_get_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()
• invalid element block ID.
• a warning value is returned if no attributes are stored in the file.

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.
[out]	attrib	Size [num_elem_this_blk*num_attr]. Returned list of(num_attr x num_elem_this_blk) attributes for the element block, with the num_attr index cycling faster.

Refer to the code example in ex_get_elem_block() for an example of reading the element attributes for an element block.
