Function Documentation

ex_get_elem_blk_ids()

int ex_get_elem_blk_ids	(	int	exoid,
		void_int *	ids
	)

Deprecated:

Use ex_get_ids()(exoid, EX_ELEM_BLOCK, ids) instead

The function ex_get_elem_blk_ids() reads the IDs of all of the element blocks. Memory must be allocated for the returned array of ({num_elem_blk}) IDs before this function is invoked. The required size(num_elem_blk) can be determined via a call to ex_inquire() or ex_inquire_int().

Returns

In case of an error, ex_get_elem_blk_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()

Parameters

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

The following code segment reads all the element block IDs:

int error, exoid, *idelbs, num_elem_blk;
idelbs = (int *) calloc(num_elem_blk, sizeof(int));
 
error = ex_get_elem_blk_ids (exoid, idelbs);
 
/* Same result using non-deprecated functions */
error = ex_get_ids (exoid, EX_ELEM_BLOCK, idelbs);
