Return ``True`` if pathname *path* is a :dfn:`mount point`: a point in a
file system where a different file system has been mounted. On POSIX, the
function checks whether *path*'s parent, :file:`path/..`, is on a different
device than *path*, or whether :file:`path/..` and *path* point to the same
function checks whether *path*'s parent, :file:`{path}/..`, is on a different
device than *path*, or whether :file:`{path}/..` and *path* point to the same
i-node on the same device --- this should detect mount points for all Unix
and POSIX variants. On Windows, a drive letter root and a share UNC are
and POSIX variants. It is not able to reliably detect bind mounts on the
same filesystem. On Windows, a drive letter root and a share UNC are
always mount points, and for any other path ``GetVolumePathName`` is called
to see if it is different from the input path.
