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

DEFAULT

PROTOCOLS

HTTP(S), FTP(S), SFTP, FILE, SMB(S)

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);
}
