Yes, this is good. When using PTY's this is definitely output-only. No one
should be using the ancient manually allocated pre-Unix98 TTYs. I'd not come
across posix_openpt() before though - I'm used to openpty(). Since this is
a Linux specific driver though, there's no portability issues to worry about
so I'm happy with either.
