How to set up timeout

[Franciszek Juras <franciszekjuras@xxxxxxxxx>]

Hi,
I noticed, that functions like ssh_channel_request_exec or sftp_open never
return (or it takes very long time - didn't wait) if the connection is
lost. I tried setting SSH_OPTIONS_TIMEOUT with ssh_options_set, but it
didn't change anything.

So how can I prevent functions from blocking forever? Why only few
functions have *_timeout versions?

Regards,
