.TH CURLINFO_CONDITION_UNMET 3 "1 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
.SH NAME
CURLINFO_CONDITION_UNMET \- get info on unmet time conditional
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONDITION_UNMET, long *unmet);
.SH DESCRIPTION
Pass a pointer to a long to receive the number 1 if the condition provided in
the previous request didn't match (see \fICURLOPT_TIMECONDITION(3)\fP). 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.
.SH PROTOCOLS
HTTP and some
.SH EXAMPLE
.nf
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":"");
}
}
