xcb_generic_iterator_t xcb_sync_systemcounter_end | ( | xcb_sync_systemcounter_iterator_t | i | ) |

Return the iterator pointing to the last element

Parameters

  i | An xcb_sync_systemcounter_iterator_t

Returns
  The iterator pointing to the last element

Set the current element in the iterator to the last element. The member rem is set to 0. The member data points to the last element.
