NAME
CURLINFO_FILETIME - get the remote time of the retrieved document
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME, long *timep);
DESCRIPTION
Pass a pointer to a long to receive the remote time of the retrieved
document (in number of seconds since 1 jan 1970 in the GMT/UTC time
zone). If you get -1, it can be because of many reasons (it might be
unknown, the server might hide it or the server does not support the
command that tells document time etc) and the time of the document is
unknown.
You must tell libcurl to collect this information before the transfer
is made, by using the CURLOPT_FILETIME(3) option to curl_easy_setopt(3)
or you will unconditionally get a -1 back.
Consider using CURLINFO_FILETIME_T(3) to be able to extract dates
beyond the year 2038 on systems using 32 bit longs.
PROTOCOLS
HTTP(S), FTP(S), SFTP
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);
}
AVAILABILITY
Added in 7.5
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
