curl timeout problem

Hi,
I'm having a problem with the cURL library.
It doesn't seem to obey the 'timeout' parameters.

I set the CURLOPT_CONNECTTIMEOUT to, say, 1 second,
and CURLOPT_TIMEOUT to whatever value.

Then I'm fetching (via a GET request) some page
from a _nonexistent_ domain - and I have to wait around 4 seconds
for the timeout error to show up. (name lookup error)

So - what's the use of CONNECTTIMEOUT and TIMEOUT?
Why I have to wait 4 seconds, while I set the connect timeout
to 1 second?

TIA, Regards

Well, maybe looking up an ip for the host might not be counted as valid
for the timeout (which might be time to let the server respond, and we
first have to know that server). What happens if you choose a
non-existent ip instead of DNS?

Sorry, my mistake.
CURL timeout works fine - the problem was that I've set a fractional
timeout - like 0.4 seconds - then the timeouts were strange.
When I now set it to 1,2 or 3 seconds then it timeouts OK.
Checked for domain lookups and IPs.

So actually the question is, if it's possible to set a fractional timeout.

Can you show me the code ..
