SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FILETIME, long gettime);

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)  argu-
       ment can be used after a transfer to extract the received time (if any).

DEFAULT

       0

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);
       }
