Is it not possible for a non-blocking read to return 0 when there is no
data to read but in actual fact the remote side has sent an EOF?
In non-blocking mode when I get a 0, I could confirm that eof has been
sent by calling libssh2_channel_eof.
There could be a slight chance that I could loose data during the time
delay from the eof call.
So I think it would be slicker to return LIBSSH2_ERROR_CHANNEL_CLOSED
rather than 0.
What are your thoughts on this?

But isn't a return code of 0 basically implying that the end of the
transfer
is reached anyway? Can it actually return 0 in any other situation?
