# CURLMOPT\_QUICK\_EXIT(3)

allow libcurl to exit quickly

## NAME

CURLOPT\_QUICK\_EXIT - allow libcurl to exit quickly

## SYNOPSIS

```
#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_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

20\.

## PROTOCOLS

This functionality affects all supported protocols

## EXAMPLE

```
int main(void)
{
  CURLM *m = curl_multi_init();
  /* do not join threads when cleaning up this multi handle */
  curl_multi_setopt(m, CURLMOPT_QUICK_EXIT, 1L);
}
```

## AVAILABILITY

Added in curl 8.20.0

## RETURN VALUE

*[curl\_multi\_setopt(3)](/curl_multi_setopt/3.md)* returns a CURLMcode indicating success or error.

CURLM\_OK (0) means everything was OK, non-zero means an error occurred, see *[libcurl-errors(3)](/libcurl-errors/3.md)*.
