/**
 * <p>Modify the version-specific settings of a Lambda function.</p>
 *
 *          <p>When you update a function, Lambda provisions an instance of the function and its supporting resources. If
 *       your function connects to a VPC, this process can take a minute. During this time, you can't modify the function,
 *       but you can still invoke it. The <code>LastUpdateStatus</code>, <code>LastUpdateStatusReason</code>, and
 *         <code>LastUpdateStatusReasonCode</code> fields in the response from <a>GetFunctionConfiguration</a>
 *       indicate when the update is complete and the function is processing events with the new configuration. For more
 *       information, see <a href="https://docs.aws.amazon.com/lambda/latest/dg/functions-states.html">Function
 *       States</a>.</p>
 *
 *          <p>These settings can vary between versions of a function and are locked when you publish a version. You can't
 *       modify the configuration of a published version, only the unpublished version.</p>
 *
 *          <p>To configure function concurrency, use <a>PutFunctionConcurrency</a>. To grant invoke permissions
 *       to an account or Amazon Web Services service, use <a>AddPermission</a>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { LambdaClient, UpdateFunctionConfigurationCommand } from "@aws-sdk/client-lambda"; // ES Modules import
 * // const { LambdaClient, UpdateFunctionConfigurationCommand } = require("@aws-sdk/client-lambda"); // CommonJS import
 * const client = new LambdaClient(config);
 * const command = new UpdateFunctionConfigurationCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link UpdateFunctionConfigurationCommandInput} for command's `input` shape.
 * @see {@link UpdateFunctionConfigurationCommandOutput} for command's `response` shape.
 * @see {@link LambdaClientResolvedConfig | config} for LambdaClient's `config` shape.
