hi,
So another newbie question just to confirm: after reading the docs
more one doesnt actually send files, even in the case below its
actually always buffer?
 curl_mime *mime;
curl_mimepart *part;
// create a mime handle
mime = curl_mime_init(easy);
// add a part
part = curl_mime_addpart(mime);
// send data from this file
curl_mime_filedata(part, "image.png");
// set name
curl_mime_name(part, "data");
