If you're using libcurl as a win32 DLL, you MUST use the CURLOPT_WRITEFUNCTION
if you set CURLOPT_WRITEDATA - or you will experience crashes.

Now, we need to take a step back and have a deep breath. Here's one of those
rare platform-dependent nitpicks. Did you spot it? On some platforms[2],
libcurl won't be able to operate on files opened by the program. Thus, if you
-use the default callback and pass in a an open file with CURLOPT_WRITEDATA, it
-will crash. You should therefore avoid this to make your program run fine

There are of course many more options you can set, and we'll get back to a few
of them later. Let's instead continue to the actual transfer:
