curl-multi-info-read not functioning

Hello! I am writing a php-cgi server, using curl-multi. It needs to start a bunch of curl 'threads', and steadily process the results of finished 'threads' and start new ones in their place. It seems to be working other than curl_multi_info_read() - this function does not return any data so I cannot see which curl threads have finished and are ready for processing. Looking at the curl.haxx.se curl-lib docs, it doesn't look too complicated (I'm not a C programmer though!) to implement, seeing as everything else is working. Perhaps I have missed something entirely. I assume it is the same problem as mentioned here:? http://marc.theaimsgroup.com/?l=php-dev&m=104791992407964&w=2 Thank you in advance for any help or suggestions you can offer, or perhaps even an ETA on when this function might be finished so I can either wait, or skin the cat another way. Warm regards, Jason
