CURLOPT_INFILESIZE_LARGE(3)         libcurl        CURLOPT_INFILESIZE_LARGE(3)


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 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

EXAMPLE

       CURL *curl = curl_easy_init();

         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
