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 specified 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 option 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);
}
}

HISTORY

CURL_TIMECOND_* enums became long types in 8.13.0, prior to this version a long cast was necessary when passed to curl_easy_setopt(3).

AVAILABILITY

Added in curl 7.59.0

RETURN VALUE

curl_easy_setopt(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non−zero means an error occurred, see libcurl−errors(3).
