See the file upload example in the cURL docs and change the protocol from file to whatever you want to use: http://curl.haxx.se/libcurl/c/fileupload.html. Note that CURLOPT_UPLOAD will send a PUT request when doing HTTP.

Or check out the FTP upload example: http://curl.haxx.se/libcurl/c/ftpupload.html
