.TH CURLINFO_FILETIME 3 "25 Jan 2018" "libcurl 7.59.0" "curl_easy_getinfo options"
|
||
|
|
.SH NAME
|
||
|
|
CURLINFO_FILETIME_T \- get the remote time of the retrieved document
|
||
|
|
.SH SYNOPSIS
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME_T, curl_off_t *timep);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Pass a pointer to a curl_off_t 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 doesn't 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 \fICURLOPT_FILETIME(3)\fP option to \fIcurl_easy_setopt(3)\fP or
|
||
|
|
you will unconditionally get a -1 back.
|
||
|
|
|
||
|
|
This option is an alternative to \fICURLINFO_FILETIME(3)\fP to allow systems
|
||
|
|
with 32 bit long variables to extract dates outside of the 32bit timestamp
|
||
|
|
range.
|
||
|
|

||
|
|
