CURLOPT_QUICK_EXIT(3) Introduction to Library Functions
CURLOPT_QUICK_EXIT - allow libcurl to exit quickly
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_QUICK_EXIT,
long value);
Pass a long as a parameter, 1L meaning that when recovering from a
timeout, libcurl should skip lengthy cleanups that are intended to
avoid all kinds of leaks (threads etc.), as the caller program is
about to call exit() anyway. This allows for a swift termination
after a DNS timeout for example, by canceling and/or forgetting about
a resolver thread, at the expense of a possible (though short-lived)
leak of associated resources.

NAME
CURLOPT_QUICK_EXIT - allow libcurl to exit quickly
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_QUICK_EXIT,
long value);
DESCRIPTION
Pass a long as a parameter, 1L meaning that when recovering from a
timeout, libcurl should skip lengthy cleanups that are intended to
avoid all kinds of leaks (threads etc.), as the caller program is
about to call exit() anyway. This allows for a swift termination
after a DNS timeout for example, by canceling and/or forgetting about
a resolver thread, at the expense of a possible (though short-lived)
leak of associated resources.
