It's posix_openpt, not posix_openpty. It exists in ArchLinux and in Debian
(probably in all other linux distros). man(3) openpty says it is not POSIX but
a BSD function. I was somewhat surprised, given your dislike of *BSD :)
man(3) posix_openpty says in NOTES how it can be implemented. The usage of
posix_openpty is associated with grantpt, ptsname and unlockpt, which you have
in libugly/. So, the interfaces for posix_openpty and openpty are different,
and I need to decide which one to use (comments about this would be
appreciated), this being my first attempt to mess with ttys.

The deprecated talk comes from man (7) pty. Maybe I misunderstood, and "BSD
pseudoterminals being deprecated" doesn't equal "openpty() being deprecated".
