Function Documentation

t8_gloidx_t *t8_cmesh_get_attribute_gloidx_array(const t8_cmesh_t cmesh, const int package_id, const int key, const t8_locidx_t ltree_id, const size_t data_count)

Return the attribute pointer of a tree for a gloidx_t array.

t8_cmesh_set_attribute_gloidx_array

Note

cmesh must be committed before calling this function.

Note

No check is performed whether the attribute actually stored data_count many entries since we do not store the number of data entries of the attribute array. You can keep track of the data count yourself by using another attribute.

Parameters:

cmesh – [in] The cmesh.
package_id – [in] The identifier of a valid software package.
key – [in] A key used to identify the attribute under all attributes of this tree with the same package_id.
ltree_id – [in] The local number of the tree.
data_count – [in] The number of entries in the array that are requested. This must be smaller or equal to the data_count parameter of the corresponding call to t8_cmesh_set_attribute_gloidx_array

Returns:

The attribute pointer of the tree ltree_id or NULL if the attribute is not found.
