.TH CURLOPT_FILETIME 3 "17 Jun 2014" libcurl libcurl
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_FILETIME \- get the modification time of the remote resource
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||

.SH 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 \fIcurl_easy_getinfo(3)\fP
|
||
|
|
function with the \fICURLINFO_FILETIME(3)\fP argument can be used after a
|
||
|
|
transfer to extract the received time (if any).
|
||
|

|
|
0
