I am using curl_multi_wait() + curl_multi_perform() to perform

Does libcURL multi interface allow user to configure it to restrict to
strictly use only one TCP connection across easy handles being added ?
If it does, are there any example programs ?
Check out CURLMOPT_MAX_HOST_CONNECTIONS [1]. Enable it on the multi
handle via curl_multi_setopt. There may be some caveats if
CURLMOPT_PIPELINING is enabled as well. It was discussed last year [2]
but I'm not sure of the status.
If it doesn't, is it inappropriate to just set options via
curl_easy_setopt (including CONNECT_ONLY) and get the libcURL socket
using CURLINFO_LASTSOCKET and do own send(), recv() instead of
curl_easy_perform to avoid blocking call ?
Don't reinvent the wheel ok :)
