# NAME
|
||
|
|
|
||
|
|
CURLOPT_FILETIME - get the modification time of the remote resource
|
||
|
|
|

|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FILETIME, long gettime);

# DESCRIPTION
|
||
|
|
|
||
|
|
Pass a long. If it is 1, libcurl attempts to get the modification time of the
|
||
|
|
remote document in this operation. This requires that the remote server sends
|
||
|
|
the time or replies to a time querying command. The curl_easy_getinfo(3)
|
||
|
|
function with the CURLINFO_FILETIME(3) argument can be used after a
|
||
|
|
transfer to extract the received time (if any).
|
||
|
