@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}.
