NAME

       CURLOPT_INFILESIZE_LARGE - size of the input file to send off

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE_LARGE,
                                 curl_off_t 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 curl_off_t.

       For uploading using SCP, this option or CURLOPT_INFILESIZE(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 actually sends, 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

       Unset

         if(curl) {
           curl_off_t uploadsize = FILE_SIZE;

           curl_easy_setopt(curl, CURLOPT_URL,
                            "ftp://example.com/destination.tar.gz");

           curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);

           curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, uploadsize);
