+# NAME
+
+CURLOPT_QUICK_EXIT - allow libcurl to exit quickly
+
+# SYNOPSIS
+
+~~~c
+#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.
+
+# DEFAULT
+
+0
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode ret;
+    curl_easy_setopt(curl, CURLOPT_QUICK_EXIT, 1L);
+    ret = curl_easy_perform(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
