26 CURLINFO_FILETIME \- get the remote time of the retrieved document
28 #include <curl/curl.h>
30 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME, long *timep);
32 Pass a pointer to a long to receive the remote time of the retrieved document
33 (in number of seconds since 1 jan 1970 in the GMT/UTC time zone). If you get
34 -1, it can be because of many reasons (it might be unknown, the server might
35 hide it or the server doesn't support the command that tells document time
36 etc) and the time of the document is unknown.
38 You must tell libcurl to collect this information before the transfer is made,
39 by using the \fICURLOPT_FILETIME(3)\fP option to \fIcurl_easy_setopt(3)\fP or
40 you will unconditionally get a -1 back.
42 Consider using \fICURLINFO_FILETIME_T(3)\fP to be able to extract dates beyond
43 the year 2038 on systems using 32 bit longs.

50 curl_easy_setopt(curl, CURLOPT_URL, url);
51 /* Ask for filetime */
52 curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
53 res = curl_easy_perform(curl);
55 res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
56 if((CURLE_OK == res) && (filetime >= 0)) {
57 time_t file_time = (time_t)filetime;
58 printf("filetime %s: %s", filename, ctime(&file_time));
62 curl_easy_cleanup(curl);
68 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
