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

PROTOCOLS

EXAMPLE

       #define FILE_SIZE 123456

       int main(void)
       {
         CURL *curl = curl_easy_init();
         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);

           curl_easy_perform(curl);
         }
       }
