I do it all completely from scratch every single time. Because when you download libraries from the web. You'll need to know how all the setting work in VS. There's no such thing as copy and paste out there in the "real world". And people who write these libraries are the worst at communication.
It's not hard at all. It's only hard when people can't communicate clearly and properly. There's files all over the place, and several things needing to be set up in VS for it all to work.
This stuff has to be communicated to the users clearly. I have noticed that information is very unclear. Cryptic sentences and, above all, almost all assume that is a veteran programmer reading them. Newbies try to read them and can't make anything out of it. I have dozens of browser tabs with stuff related to curl but most of them I can't decipher properly :- Well, I guess I have something to start with, now.
Oh, by the way, my code was mostly what I could come up with after reading a LOT about curl. However, I start my development in Xcode. So, I still need to find out how to compile it for Mac, first. Actually, on my Mac, I was just including the curl library that is already in my system. But I guess it is not enough. Well, off I go, trying to find out how to compile it for Mac. Hello again, Scott.
I have it all working fine now in MacOS X. It was not easy but it is working perfectly now. Now I was trying to build the Win32 and Win64 versions.
All rights reserved. Must I have the curl folder in some specific place? Compiling curl in MacOS was so easy. Note : Nevertheless, curl provides multiple options for verifying server certificates. 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. 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. I implemented this. But I do not know how to implement the server side.

Viewed 6k times. Improve this question. Have you checked the MSDN for documentation? That should give you a hint how it operates and how to implement the server-side of this. This event occurs when an asynchronous download operation successfully transfers some or all of the data. You can use the CancelAsync method to cancel asynchronous operations that have not completed. To block while waiting for the download to complete, use one of the DownloadFile discuss in above methods.
