CURLOPT_INFILESIZE_LARGE(3)curl_easy_setopt optionsCURLOPT_INFILESIZE_LARGE(3)

NAME
       CURLOPT_INFILESIZE_LARGE - set 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 manda-
       tory.

       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_easy_setopt(curl, CURLOPT_UPLOAD, 1L);

         curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, uploadsize);

         curl_easy_perform(curl);
       }

AVAILABILITY
       SMTP support added in 7.23.0
