# NAME
|
|
|
|
CURLOPT_TIMEVALUE - time value for conditional
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEVALUE, long val);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a long *val* as parameter. This should be the time counted as seconds
|
|
since 1 Jan 1970, and the time is used in a condition as specified with
|
|
CURLOPT_TIMECONDITION(3).
|
|
|
|
On systems with 32-bit 'long' variables (such as Windows), this option cannot
|
|
set dates beyond the year 2038. Consider CURLOPT_TIMEVALUE_LARGE(3)
|
|
instead.
