NAME

     CURLINFO_CONDITION_UNMET - get info  on  unmet  time  condi-
     tional


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 con-
     dition  provided  in  the previous request didn't match (see
     CURLOPT_TIMECONDITION(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 ths  argu-
     ment  points  to  will  get  a  zero stored if the condition
     instead was met.


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":"");
         }
       }
     }
