Get the name of the slave pseudoterminal (see
ptsname(3))
ptsname_r() returns the name of the slave pseudoterminal device corresponding to the master
referred to by fd. This is the threadsafe version of ptsname(), but it is not part of the
POSIX standard and is instead a Linux-specific extension.
This value is useful for opening the slave ptty once the master has already been opened with
posix_openpt().
