@node Inode numbers on Windows
@section Inode numbers on Windows

The module @samp{windows-stat-inodes} ensures that,
on native Windows platforms, @code{struct stat} contains
@code{st_dev}, @code{st_ino} fields that are able to distinguish
different inodes.

Note: Such values can only be provided for most files on the
file system.  For a few files (such as inaccessible files),
@code{st_dev} and @code{st_ino} are set to 0.  Therefore,
you should test whether @code{st_dev != 0 && st_ino != 0},
before going to make inferences based on the file identity
based on @code{st_dev} and @code{st_ino}.
