Updates the configuration parameters for the specified Lambda function by using the values provided in the request. You provide only the parameters you want to change. This operation must only be used on an existing Lambda function and cannot be used to update the function's code.

If you are using the versioning feature, note this API will always update the $LATEST version of your Lambda function. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases.

This operation requires permission for the lambda:UpdateFunctionConfiguration action.

Note:

For PCL and Unity this operation is only available in asynchronous form. Please refer to UpdateFunctionConfigurationAsync.

Namespace: Amazon.Lambda

    Runtime = "python2.7",
    Timeout = 123,
    VpcConfig = new VpcConfig {  }
});

string codeSha256 = response.CodeSha256;
long codeSize = response.CodeSize;
string description = response.Description;
string functionArn = response.FunctionArn;
string functionName = response.FunctionName;
string handler = response.Handler;
string lastModified = response.LastModified;
integer memorySize = response.MemorySize;
