+ *
+ * Connecting:
+ * - RNET_MEMORY_ERR    No buffer space is available. The socket cannot be connected.
+ * - RNET_NET_UNREACHABLE  The network cannot be reached from this host at this time.
+ * - RNET_TIMEOUT      Attempt to connect timed out without establishing a connection
+ * - RNET_CONN_REFUSED    The attempt to connect was forcefully rejected.
+ * - RNET_NOT_SUPPORTED    Addresses in the specified family cannot be used with this socket.
+ * Closing:
+ * - RNET_INTERNAL_ERR    The network subsystem has failed.
+ * - RNET_CONN_RESET    The connection was reset by the remote side
+ * - RNET_CONN_ABORTED    The connection was terminated due to a time-out or other failure.
+ * - RNET_CONN_CLOSED    The connection was gracefully closed (not an error actually)..
+ *
+ * @param  desc  Connection identifier.
+ * @param  error  Error code.
