.TH CURLINFO_FILETIME 3 "28 Aug 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
|
|
.SH NAME
|
|
CURLINFO_FILETIME \- get the remote time of the retrieved document
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME, long *timep);
|
|
.SH 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 doesn't support the command that tells document time
|
|
etc) and the time of the document is unknown.
|
|
|
|
Note that you must tell the server 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.
|
|
