Hello,
When using curl_easy_recv(), what is the correct way to determine if the
peer has disconnected?

When using the socket API, recv() will return a length of 0 when the peer
has disconnected. In my own testing, it looks like curl_easy_recv() will
return CURLE_UNSUPPORTED_PROTOCOL (1) in this case, but that does not seem
to be documented anywhere. Is that the correct error code to look for?

Also, rarely, curl_easy_recv() will return CURLE_OK, but set n=0. What does
this mean? Does it also mean the peer has disconnected?

Thank you
