.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.
