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

       Unset

PROTOCOLS

       Many

EXAMPLE

       CURL *curl = curl_easy_init();

         curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);

         curl_easy_setopt(curl, CURLOPT_INFILESIZE, uploadsize);

         curl_easy_perform(curl);
       }
