NAME

SYNOPSIS

9       #include <curl/curl.h>

11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FILETIME, long gettime);
12

DESCRIPTION

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

31         curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
32         res = curl_easy_perform(curl);
33         if(CURLE_OK == res) {
34           res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
35           if((CURLE_OK == res) && (filetime >= 0)) {
36             time_t file_time = (time_t)filetime;
37             printf("filetime %s: %s", filename, ctime(&file_time));
38           }
