+ * The network layer may receive chopped up messages since TCP is a streaming
+ * protocol. Furthermore, the networklayer may operate on ringbuffers or
+ * statically assigned memory.
+ *
+ * If an entire message is received, it is forwarded directly. But the memory
+ * needs to be freed with the networklayer-specific mechanism. If a half message
+ * is received, we copy it into a local buffer. Then, the stack-specific free
+ * needs to be used.
+ *
+ * @param connection The connection
+ * @param message The received message. The content may be overwritten when a
+ *        previsouly received buffer is completed.
+ * @param realloced The Boolean value is set to true if the outgoing message has
+ *        been reallocated from the network layer.
+ * @return Returns UA_STATUSCODE_GOOD or an error code. When an error occurs, the ingoing message
+ *         and the current buffer in the connection are freed.
