By default, curl will print downloaded data to the console, which is useful for testing purposes. Once the request is executed, libcurl will check everything for errors and output the error string to the std::cerr object.

In asynchronous file downloading, all requests are executed in an arbitrary order. For asynchronous downloading, we still need to create curl easy handles and set options for them.

So the first seven steps will be the same as for synchronous downloading. However, asynchronous downloading in libcurl can be achieved through the curl-multi interface.

With a multi handle and the curl-multi interface, you can perform several simultaneous transfers in parallel. In this case, every separate transfer will be built around a separate curl easy handle. Using the created guard, we can now create a curl multi handle.
