NAME

CURLOPT_QUICK_EXIT - allow libcurl 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.

DEFAULT

PROTOCOLS

This functionality affects all supported protocols

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_QUICK_EXIT, 1L);
    result = curl_easy_perform(curl);
  }
}

AVAILABILITY

Added in curl 7.87.0

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).
