+ *
+ * An application should always have a matching call to rnet_close for each successful
+ * call to rnet_new to return any resources to the system.
+ *
+ * The function may return RNET_MEMORY_ERR if no memory
+ * was available for closing the connection. If so, the application
+ * should wait and try again either by using the error message
+ * or the polling functionality.
+ * If the close succeeds, the function returns RNET_OK.
+ *
+ * The connection ID is deallocated after a call to rnet_close().
+ *
+ * @param  desc  Connection identifier.
+ * @return  RNET_MEMORY_ERR      Not enough memory is available
+ *      RNET_NOT_INITIALIZED  NET subsystem not initialized (internal error).
+ *      RNET_INTERNAL_ERR    Network subsystem failed.
+ *      RNET_INVALID_PARAMETER  The connection ID is invalid.
+ *      RNET_NOT_READY      Still processing a callback function.
+ *      RNET_OK          Socket closed.
