wouldn't it be much easier interface to just have a

CURL **handles = curl_multi_get_handles(multi);

where the last position in *handles would be NULL to indicate the end? Yes
it would require libcurl to allocate a list and populate it at the call,

complete list at once avoids the problem with adds/dels during iteration of
the list.
