CURLINFO_FILETIME(3) curl_easy_getinfo options CURLINFO_FILETIME(3)
NAME
CURLINFO_FILETIME_T - get the remote time of the retrieved document
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME_T,
curl_off_t *timep);
DESCRIPTION
Pass a pointer to a curl_off_t to receive the remote time of the re-
trieved 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 ask 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.
This option is an alternative to CURLINFO_FILETIME(3) to allow systems
with 32 bit long variables to extract dates outside of the 32bit time-
stamp range.
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) {
curl_off_t filetime;
res = curl_easy_getinfo(curl, CURLINFO_FILETIME_T, &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 7.59.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
