It is--but it's begin sent encrypted so you need to use libssh2 to read it.

The documentation for those function describes how to use them. The following
brute-force hack to the ssh2 example program will display the first bit
of data sent by the remote server after a shell connect just to prove that
it's possible:

A real implementation would be built on libssh2_poll instead of this
dumb busy loop.
It would probably be a good idea to update the ssh2 example program to
actually behave more like OpenSSH's ssh and allow an actual interactive
login session.
