23 .TH CURLINFO_CONDITION_UNMET 3 "1 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
24 .SH NAME
25 CURLINFO_CONDITION_UNMET \- get info on unmet time conditional
26 .SH SYNOPSIS
27 #include <curl/curl.h>
28
29 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONDITION_UNMET, long *unmet);
30 .SH DESCRIPTION
31 Pass a pointer to a long to receive the number 1 if the condition provided in
32 the previous request didn't match (see \fICURLOPT_TIMECONDITION(3)\fP). Alas,
33 if this returns a 1 you know that the reason you didn't get data in return is
34 because it didn't fulfill the condition. The long this argument points to will
35 get a zero stored if the condition instead was met.
36 .SH PROTOCOLS
37 HTTP and some
