CURLOPT_QUICK_EXIT explained

Name

CURLOPT_QUICK_EXIT - allow 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.

    ret = curl_easy_perform(curl);
  }
}
