NAME

       CURLINFO_CONDITION_UNMET - get info on unmet time conditional

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 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 argument 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":"");
           }
         }
       }
