.SH NAME
|
|
CURLINFO_CONDITION_UNMET \- get info on unmet time conditional or 304 HTTP response.
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONDITION_UNMET,
|
|
long *unmet);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a long to receive the number 1 if the condition provided in
|
|
the previous request did not match (see \fICURLOPT_TIMECONDITION(3)\fP). Alas,
|
|
if this returns a 1 you know that the reason you did not get data in return is
|
|
because it did not fulfill the condition. The long this argument points to
|
|
gets a zero stored if the condition instead was met. This can also return 1 if
|
|
the server responded with a 304 HTTP status code, for example after sending a
|
|
custom "If\-Match\-*" header.
