Overview

1 N 4 1
101 Node ID Creation

Encode a reference object (an object generated with make_ref/0). The Node term is an encoded atom, i.e. ATOM_EXT, SMALL_ATOM_EXT or ATOM_CACHE_REF. The ID field contains a big-endian unsigned integer, but should be regarded as uninterpreted data since this field is node specific. Creation is a byte containing a node serial number that makes it possible to separate old (crashed) nodes from a new one.

In ID, only 18 bits are significant; the rest should be 0. In Creation, only 2 bits are significant; the rest should be 0. See NEW_REFERENCE_EXT.
