Using that API you can know how much data that is already read off the socket
and is waiting for you to get read, yes.

I would do it simpler. I would just do this:

  select() on socket

  if(readable) {

    for(loop over all channels) {

      rc = libssh2_channel_read_ex( channel [check index] ...);

      ...
    }
  }
