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
       This functionality affects http only

EXAMPLE
       int main(void)
       {
	 CURL *curl = curl_easy_init();
	 if(curl) {
	   curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

	   /* January 1, 2020 is 1577833200 */
	   curl_easy_setopt(curl, CURLOPT_TIMEVALUE_LARGE, (curl_off_t)1577833200);

	   /* If-Modified-Since	the above time stamp */
	   curl_easy_setopt(curl, CURLOPT_TIMECONDITION, CURL_TIMECOND_IFMODSINCE);

	   /* Perform the request */
	   curl_easy_perform(curl);
	 }
       }
