.. function:: ismount(path)
Return ``True`` if pathname *path* is a :dfn:`mount point`: a point in a file
system where a different file system has been mounted. The function checks
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 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 always mount
points, and for any other path ``GetVolumePathName`` is called to see if it
is different from the input path.

Support for detecting non-root mount points on Windows.
