CURLOPT_TIMEVALUE(3)

NAME
CURLOPT_TIMEVALUE - time value for conditional

SYNOPSIS
#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.

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, 1577833200L);
    /* If-Modified-Since the above time stamp */
    curl_easy_setopt(curl, CURLOPT_TIMECONDITION, CURL_TIMECOND_IFMODSINCE);
    /* Perform the request */
    curl_easy_perform(curl);
  }
}

AVAILABILITY
