CURLINFO_CONDITION_UNMET(3)curl_easy_getinfo optionCURLINFO_CONDITION_UNMET(3)

NAME
       CURLINFO_CONDITION_UNMET	 -  get	 info on unmet time conditional	or 304
       HTTP response.

SYNOPSIS
       #include	<curl/curl.h>

       CURLcode	curl_easy_getinfo(CURL *handle,	CURLINFO_CONDITION_UNMET, long
       *unmet);

DESCRIPTION
       Pass  a pointer to a long to receive the	number 1 if the	condition pro-
       vided in	the previous  request  didn't  match  (see  CURLOPT_TIMECONDI-
       TION(3)). Alas, if this returns a 1 you know that the reason you	didn't
       get data	in return is because it	didn't fulfill the condition. The long
       this argument points to will get	a zero stored if the condition instead
       was met.	This can also return 1 if the server responded with a 304 HTTP
       status code, for	example	after sending a	custom "If-Match-*" header.

PROTOCOLS
       HTTP and	some

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl)	{
	 curl_easy_setopt(curl,	CURLOPT_URL, "http://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	*/
	 res = curl_easy_perform(curl);

	 if(!res) {
	   /* check the	time condition */
	   long	unmet;
	   res = curl_easy_getinfo(curl, CURLINFO_CONDITION_UNMET, &unmet);
	   if(!res) {
	     printf("The time condition	was %sfulfilled\n", unmet?"NOT":"");
	   }
	 }
       }
