kv_parallel_scan_iterator_next()
#include <kvstore.h>
kv_error_t
kv_parallel_scan_iterator_next(kv_parallel_scan_iterator_t *iterator,
const kv_key_t **key,
const kv_value_t **value) Returns the iterator's next record. If another record exists, this function returns KV_SUCCESS, and the key and value parameters are populated. If there are no more records, the return value is KV_NO_SUCH_OBJECT. If the return value is something other than KV_SUCCESS or KV_NO_SUCH_OBJECT, there was an operational failure.
Parameters
-
iterator
The iterator parameter is the handle to the iterator. It is allocated using kv_parallel_store_iterator(). It is released using kv_release_parallel_scan_iterator().
-
key
The key parameter references memory in which a pointer to the next key is copied.
Note, you should not release this key structure. The resources used here will be released when the iterator is released.
-
value
The value parameter references memory in which a pointer to the next value is copied.
Note, you should not release this value structure. The resources used here will be released when the iterator is released.
