Hi Daniel,

Thanks Daniel for you quick response.
I am going to use for a high performance load testing.As per you
information curl_multi_perform() API will return once all easy handle
transfer the data.So It will block the operation to complete the transfer
for all easy handle.

In my project we need, if first time the data transfer is not complete then
we will call next time based on the notification of data availability. My
application will create huge no of child process and each child process
will invoke curl_multi_perform().So I need more clarification regarding
below API.

Is curl_multi_perform() API working as a non-blocking mode or blocking mode
?

Thanks,
Smruti
