CURLINFO_FILETIME_T(3) Library Functions Manual CURLINFO_FILETIME_T(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
retrieved document in number of seconds since January 1 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 or you 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 32-bit
timestamp range.
PROTOCOLS
This functionality affects ftp, http and sftp
EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
/* 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", ctime(&file_time));
}
}
/* always cleanup */
curl_easy_cleanup(curl);
}
}
AVAILABILITY
Added in curl 7.59.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
