Method BatchLookup

map.go:1245–1251

BatchLookup looks up many elements in a map at once. "keysOut" and "valuesOut" must be of type slice, a pointer to a slice or buffer will not work. "cursor" is an pointer to an opaque handle. It must be non-nil. Pass "cursor" to subsequent calls of this function to continue the batching operation i

(cursor *MapBatchCursor, keysOut, valuesOut any, opts *BatchOptions)

// the end of all possible results, even when partial results
// are returned. It should be used to evaluate when lookup is "done".
func (m *Map) BatchLookup(cursor *MapBatchCursor, keysOut, valuesOut any, opts *BatchOptions) (int, error) {
	n, err := m.batchLookup(sys.BPF_MAP_LOOKUP_BATCH, cursor, keysOut, valuesOut, opts)
	if err != nil {
		return n, fmt.Errorf("map batch lookup: %w", err)
	}
	return n, nil
}
