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 attempts 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

0

PROTOCOLS

This functionality affects file, ftp, http, sftp and smb

EXAMPLE

int main(void)
{


  CURL *curl = curl_easy_init();


  if(curl) {


    CURLcode res;


    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/path.html");


    /* Ask for filetime */


    curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);


    res = curl_easy_perform(curl);


    if(CURLE_OK == res) {


      long filetime;


      res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);


      if((CURLE_OK == res) && (filetime >= 0)) {


        time_t file_time = (time_t)filetime;


        printf("filetime: %s", ctime(&file_time));


      }


    }


    /* always cleanup */


    curl_easy_cleanup(curl);


  }
}

AVAILABILITY
