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

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

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);
}
