CURLOPT_INFILESIZE

CURLOPT_INFILESIZE is one of the accepted parameters for curl_setopt parameter #2.

CURLOPT_INFILESIZE — The expected size, in bytes, of the file when uploading a file to a remote site. Note that using this option will not stop cURL from sending more data, as exactly what is sent depends on CURLOPT_READFUNCTION. This option accepts any value that can be cast to a valid int. Available as of cURL 7.1.0.

CURLOPT_INFILESIZE = 14;
