Using the created guard, we can now create a curl multi handle. Similar to the previous example, we create three curl easy handles for downloading three sample files:. Also, this call assigns the count of currently running curl easy handles to the second argument. If this value is equal to 0, it means all operations have finished. If the value is negative, libcurl has no timeout set and we should wait, say, milliseconds. The maxfd parameter is set to the value of the maximum file descriptor.

During execution of this loop, all curl easy handles will receive data and write it to a file. You can find the code for the whole loop here. Finally, after executing all requests, we need to remove curl easy handles from the multi handle:. Multiplexing allows for reusing a single connection to one server for processing multiple HTTP requests.

This method can improve the performance of request-heavy applications by eliminating the need to close and reopen server connections. We can reuse the asynchronous example and add this code between setting options for curl easy handles and add curl easy handles to the curl multi handle step 3 in the previous section :.

If detected, such a connection will be used instead of creating a new connection. You can find the full source code of all examples from this article on our GitHub page.
