+/**
+ * fna_receive_endpoint_create()
+ *
+ * This operation creates a receive endpoint associated with a
+ * undirectional stream within a network interface of the node.
+ *
+ * Receiving endpoints are not bound to any network vres, this is
+ * because don't originate any traffic.
+ *
+ * Note that the protocol address is not needed for reception because
+ * it can be determined internally by FRSH based on the network_id.

+ * Note also that messages may come from diferent originators.
+ *
+ * @param[in] resource_id  Id of the network from which we listen.
+ * @param[in] stream_id  Id of the stream within the network.
+ * @param[in] queueing_info Buffering information(queue size and
+ *                          policy).
+ * @param[in] protocol_info Extra protocol info opaque for the
+ *                          application.
+ * @param[out] endpoint  Placeholder for the endpoint object.
+ *
+ * @return
+ *   FNA_NO_ERROR: in this case it also means contract accepted \n
+ *   FNA_ERR_INTERNAL_ERROR: protocol dependent internal errors \n
+ *   FNA_ERR_NOT_INITIALIZED: if the protocol is not initialized \n
