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 gettime);

DESCRIPTION

       Pass  a  long.  If  it is 1, libcurl attempts 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

       This functionality affects file, ftp, http, sftp and smb

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/path.html");
           /* Ask for filetime */
           curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
           res = curl_easy_perform(curl);
           if(CURLE_OK == res) {
             long filetime;
             res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
             if((CURLE_OK == res) && (filetime >= 0)) {
               time_t file_time = (time_t)filetime;
               printf("filetime: %s", ctime(&file_time));
             }
           }
           /* always cleanup */
           curl_easy_cleanup(curl);
         }
       }
