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 libcurl from sending more data, as exactly what is sent depends on CURLOPT_READFUNCTION.
