I don't want to open a new topic so i'll ask here.

libssh2 has 2 entities: session and channel, but only channel has
"eof" or "disconnected" states. I don't see something similar for
session. The question then is how could i know that session is closed
without creating a channel?
As i understand, when libssh2 does low-level reading (read or recv
call) on file handle, it doesn't store information about read/recv
returned zero bytes (connection closed) or errno value so such
information can't be used by libssh2 user.
