NAME
CURLOPT_INFILESIZE - size of the input file to send off
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE, long filesize);
DESCRIPTION
When uploading a file to a remote site, filesize should be used to tell
libcurl what the expected size of the input file is. This value must be
passed as a long. See also CURLOPT_INFILESIZE_LARGE(3) for sending
files larger than 2GB.
For uploading using SCP, this option or CURLOPT_INFILESIZE_LARGE(3) is
mandatory.
To unset this value again, set it to -1.
When sending emails using SMTP, this command can be used to specify the
optional SIZE parameter for the MAIL FROM command.
This option does not limit how much data libcurl will actually send, as
that is controlled entirely by what the read callback returns, but
telling one value and sending a different amount may lead to errors.
DEFAULT

curl_easy_setopt(curl, CURLOPT_INFILESIZE, uploadsize);

}

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
