I don't do people's homework for them but... Well there isn't a direct equivalent because in unix when you have a "terminal" session that generally means you have a "tty" devices as stdin/stdout/stderr. And, this tty device buffers input as well as things like generating signals to your process when CTRL-C is typed. You can get close though--you can use select() to determine if there's data to be read on stdin (which I'm guessing is what you want to do anyway). Here's a sample C program which demonstrates the technique.
