CURLOPT_FILETIME(3)        curl_easy_setopt options        CURLOPT_FILETIME(3)

NAME
       CURLOPT_FILETIME - get the modification time of the remote resource

SYNOPSIS
       #include <curl/curl.h>

       CURLcode  curl_easy_setopt(CURL  *handle,  CURLOPT_FILETIME,  long get-
       time);

DESCRIPTION
       Pass a long. If it is 1, libcurl will attempt to get  the  modification
       time  of  the remote document in this operation. This requires that the
       remote server sends the time or replies to a time querying command. The
       curl_easy_getinfo(3)  function  with  the CURLINFO_FILETIME(3) argument
       can be used after a transfer to extract the received time (if any).

DEFAULT
       0

PROTOCOLS
       HTTP, FTP, SFTP, FILE

EXAMPLE
       curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, url);
         /* Ask for filetime */
         curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
         res = curl_easy_perform(curl);
         if(CURLE_OK == res) {
           res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
           if((CURLE_OK == res) && (filetime >= 0)) {
             time_t file_time = (time_t)filetime;
             printf("filetime %s: %s", filename, ctime(&file_time));
           }
         }
         /* always cleanup */
         curl_easy_cleanup(curl);
       }
