A few protocols won't behave properly when uploads are done without any prior
knowledge of the expected file size. So, set the upload file size using the
CURLOPT_INFILESIZE for all known file sizes like this[1]:
CURLOPT_INFILESIZE_LARGE for all known file sizes like this[1]:
curl_easy_setopt(easyhandle, CURLOPT_INFILESIZE, file_size);

operations and when it has invoked the upload it'll call your supplied

.IP CURLOPT_MAXFILESIZE
Pass a long as parameter. This allows you to specify the maximum size (in
bytes) of a file to download. If the file requested is larger than this value,
the transfer will not start and CURLE_FILESIZE_EXCEEDED will be returned.
NOTE: The file size is not always known prior to download, and for such files
this option has no effect even if the file transfer ends up being larger than
this given limit. This concerns both FTP and HTTP transfers.
