CURLOPT_TIMEVALUE_LARGE(3) Library Functions Manual CURLOPT_TIMEVALUE_LARGE(3)
NAME
CURLOPT_TIMEVALUE_LARGE - time value for conditional
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEVALUE_LARGE,
curl_off_t val);
DESCRIPTION
Pass a curl_off_t val as parameter. This should be the time counted as
seconds since 1 Jan 1970, and the time is used in a condition as speci-
fied with CURLOPT_TIMECONDITION(3).
The difference between this option and CURLOPT_TIMEVALUE(3) is the type
of the argument. On systems where 'long' is only 32 bits wide, this op-
tion has to be used to set dates beyond the year 2038.
DEFAULT
0
PROTOCOLS

curl_easy_setopt(curl, CURLOPT_TIMEVALUE_LARGE, (curl_off_t)1577833200);
