CURLMOPT_QUICK_EXIT(3) Library Functions Manual CURLMOPT_QUICK_EXIT(3)
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) returns a CURLMcode indicating success or error.
CURLM_OK (0) means everything was OK, non-zero means an error occurred,
see libcurl-errors(3).
