26 CURLINFO_FILETIME_T \- get the remote time of the retrieved document
28 #include <curl/curl.h>
30 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME_T, curl_off_t *timep);
32 Pass a pointer to a curl_off_t to receive the remote time of the retrieved
33 document (in number of seconds since 1 jan 1970 in the GMT/UTC time zone). If
34 you get -1, it can be because of many reasons (it might be unknown, the server
35 might hide it or the server doesn't support the command that tells document
36 time etc) and the time of the document is unknown.
38 You must ask 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 This option is an alternative to \fICURLINFO_FILETIME(3)\fP to allow systems
43 with 32 bit long variables to extract dates outside of the 32bit timestamp
49 curl = curl_easy_init();
51 curl_easy_setopt(curl, CURLOPT_URL, url);
52 /* Ask for filetime */
53 curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
54 res = curl_easy_perform(curl);
57 res = curl_easy_getinfo(curl, CURLINFO_FILETIME_T, &filetime);
58 if((CURLE_OK == res) && (filetime >= 0)) {
59 time_t file_time = (time_t)filetime;
60 printf("filetime %s: %s", filename, ctime(&file_time));
64 curl_easy_cleanup(curl);
70 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
