Remove the code too. The functionality has been disabled in code since 7.62.0. Setting this option will from now on simply be ignored and have no function. Closes #3654

.TH CURLOPT_DNS_USE_GLOBAL_CACHE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_DNS_USE_GLOBAL_CACHE \- enable/disable global DNS cache
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_USE_GLOBAL_CACHE,
|
|
long enable);
|
|
.SH DESCRIPTION
|
|
Has no function since 7.62.0. Do note use!
|
|
|
|
Pass a long. If the \fIenable\fP value is 1, it tells curl to use a global DNS
|
|
cache that will survive between easy handle creations and deletions. This is
|
|
not thread-safe and this will use a global variable.
|
|
|
|
\fBWARNING:\fP this option is considered obsolete. Stop using it. Switch over
|
|
to using the share interface instead! See \fICURLOPT_SHARE(3)\fP and
|
|
\fIcurl_share_init(3)\fP.
