- * radius_client_reconfig - Reconfigure RADIUS client

- * @oldconf: Old RADIUS client configuration (RADIUS servers)
- * @newconf: New RADIUS client configuration (RADIUS servers)
- * Returns: Pointer to private RADIUS client context or %NULL on failure
- *
- * This function can be used to conditionally change RADIUS client
- * configuration. If newconf differs from oldconf, the old RADIUS client
- * context is deinitialized and new one is allocated. If there is no change in
- * the configuration, the old RADIUS client context will be returned.
- *
- * The caller is responsible for keeping the new configuration data available
- * for the lifetime of the RADIUS client, i.e., until radius_client_deinit() is
- * called for the returned context pointer.
