49 * The implementation of the Source and Replica
50 * side QIODevice look like they will be fairly
51 * different, including different APIs. So
52 * creating a 2nd derived type for the source.
53 *
54 * TODO: revisit if these can be combined into a
55 * single type.
56 *
57 * With two types, QQnxNativeIo will need to get
58 * Source or Replica added. Not sure what intuitive
59 * names are yet. So for now, QQnxNativeIo is the
60 * Replica side, QIOQnxSourcePrivate is the Source
61 * side. Revisit the name as this matures.
