CURLINFO_FILETIME(3)curl_easy_getinfo optionsCURLINFO_FILETIME(3)

NAME

     CURLINFO_FILETIME - get the remote  time  of  the  retrieved
     document

SYNOPSIS

     #include <curl/curl.h>

     CURLcode curl_easy_getinfo(CURL *handle,  CURLINFO_FILETIME,
     long *timep);

DESCRIPTION

     Pass a pointer to a long to receive the remote time  of  the
     retrieved document (in number of seconds since 1 jan 1970 in
     the GMT/UTC time zone). If you get -1, it can be because  of
     many  reasons (it might be unknown, the server might hide it
     or the server doesn't support the command that  tells  docu-
     ment time etc) and the time of the document is unknown.

     Note that you must tell the server to collect this  informa-
     tion   before   the   transfer   is   made,   by  using  the
     CURLOPT_FILETIME(3) option  to  curl_easy_setopt(3)  or  you
     will unconditionally get a -1 back.

PROTOCOLS

     HTTP(S), FTP(S), SFTP

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);
     }
