No, it isn't.

curl_multi_info_read() returns information about easy handles that are still
in the multi stack. To tell the application when a specific transfer has

When you remove the easy handle from the stack, it won't be transfered anymore
and it will therefor not complete either. It will not cause a message to be
generated at all.

You remove the easy handle from the multi handle, that effectively stopped
that transfer and prevents it from going any further. That easy handle is
still identifying a transfer that you can set new options to, reset or free.

If you want to restart the tranfer that easy handle represents, you add it to
the multi stack again.
