POSIX: https://pubs.opengroup.org/onlinepubs/9699919799/functions/ttyname.html

pub unsafe fn ttyname(fd: RawFd) -> Result<String>;
pub fn ttyname_r(fd: RawFd) -> Result<String>;

ttyname and ttyname_r are basically ptsname that works on any TTY fds, not just those associated with a PTY slave device. The latter is a pretty useful portable alternative to ptsname_r.

The functions are found on basically every nix platform; see libc crate for details about a macOS compliance fix it has.

Nix operates on a "patches welcome" basis. Us maintainers are basically just curators. Do you care to submit a patch?
