I've also been working on a project which uses libssh2 to create a shell. I don't have a good, simple example to give you, since it's a GUI program that contains code adapted from several different sources, and things are ugly right now. But, let me see if I can give an overview of how I've got things working. I have an SSHConnection class that encapsulates the socket IO. Whenever the socket reports that there's input available, I call SSHConnection->Read(void * buffer, uint nbytes). Read() does some calculations to figure out exactly how much to read from the channel, does a libssh2_poll() to confirm that it's ready to read, then creates a new char[] buffer and calls libssh2_channel_read(channel, buffer, actualNBytes). From there, you should be able to do whatever you want with the data. Writing's pretty simple. Whenever the user types, I call SSHConnection->Write(char* data, int len), which passes it on to libssh2_channel_write(channel, data, len). My project is still pretty much a throwaway test with a lot of glitches, so I don't claim to have this perfected. Still, hopefully that will give you a bit of an idea where to head.
