SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode  curl_easy_setopt(CURL  *handle,  CURLOPT_FILETIME,  long get‐
12       time);

DESCRIPTION

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

34         if(CURLE_OK == res) {
35           res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
36           if((CURLE_OK == res) && (filetime >= 0)) {
37             time_t file_time = (time_t)filetime;
