CURLOPT\_QUICK\_EXIT(3) Library Functions Manual CURLOPT\_QUICK\_EXIT(3)

# [NAME](#NAME)

CURLOPT\_QUICK\_EXIT - allow libcurl to exit quickly

# [SYNOPSIS](#SYNOPSIS)

```
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_QUICK_EXIT,


                          long value);
```

# [DESCRIPTION](#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.
