23 .TH CURLINFO_CONDITION_UNMET 3 "February 23, 2018" "libcurl 7.59.0" "curl_easy_getinfo options"
26 CURLINFO_CONDITION_UNMET \- get info on unmet time conditional
28 #include <curl/curl.h>
30 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONDITION_UNMET, long *unmet);
32 Pass a pointer to a long to receive the number 1 if the condition provided in
33 the previous request didn't match (see \fICURLOPT_TIMECONDITION(3)\fP). Alas,
34 if this returns a 1 you know that the reason you didn't get data in return is
35 because it didn't fulfill the condition. The long this argument points to will
36 get a zero stored if the condition instead was met.
41 CURL *curl = curl_easy_init();
43 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
45 /* January 1, 2020 is 1577833200 */
46 curl_easy_setopt(curl, CURLOPT_TIMEVALUE, 1577833200L);
48 /* If-Modified-Since the above time stamp */
49 curl_easy_setopt(curl, CURLOPT_TIMECONDITION, CURL_TIMECOND_IFMODSINCE);
51 /* Perform the request */
52 res = curl_easy_perform(curl);
55 /* check the time condition */
57 res = curl_easy_getinfo(curl, CURLINFO_CONDITION_UNMET, &unmet);
59 printf("The time condition was %sfulfilled\\n", unmet?"NOT":"");
67 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
