/* Example source code to show how the callback function can be used to
* download data into a chunk of memory instead of storing it in a file.
* After successful download we use curl_easy_getinfo() calls to get the
* amount of downloaded bytes, the time used for the whole download, and
* the average download speed.
* On Linux you can create the download test files with:
* dd if=/dev/urandom of=file_1M.bin bs=1M count=1
