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":""); } } }
