Hi,

Yup that answers my questions. I'm on CURL 7.19.7 (and thus have to make
use of CURL_CALL_MULTI_PERFORM). Just one more thing, so what happens to
the callback function now, Does it receive the data in a single call now
(i.e. till CURLM_OK) rather than callback getting called every time for
 curl_multi_perform ?.

Thanks for the response.

Thanks
Sunny
