    -- t'GI.Gio.Objects.FileEnumerator.FileEnumerator' allows you to operate on a set of @/GFiles/@,
    -- returning a t'GI.Gio.Objects.FileInfo.FileInfo' structure for each file enumerated (e.g.
    -- 'GI.Gio.Interfaces.File.fileEnumerateChildren' will return a t'GI.Gio.Objects.FileEnumerator.FileEnumerator' for each
    -- of the children within a directory).
    --
    -- To get the next file\'s information from a t'GI.Gio.Objects.FileEnumerator.FileEnumerator', use
    -- 'GI.Gio.Objects.FileEnumerator.fileEnumeratorNextFile' or its asynchronous version,
    -- 'GI.Gio.Objects.FileEnumerator.fileEnumeratorNextFilesAsync'. Note that the asynchronous
    -- version will return a list of @/GFileInfos/@, whereas the
    -- synchronous will only return the next file in the enumerator.
    --
    -- The ordering of returned files is unspecified for non-Unix
    -- platforms; for more information, see 'GI.GLib.Structs.Dir.dirReadName'.  On Unix,
    -- when operating on local files, returned files will be sorted by
    -- inode number.  Effectively you can assume that the ordering of
    -- returned files will be stable between successive calls (and
    -- applications) assuming the directory is unchanged.
    --
    -- If your application needs a specific ordering, such as by name or
    -- modification time, you will have to implement that in your
    -- application code.
    --
    -- To close a t'GI.Gio.Objects.FileEnumerator.FileEnumerator', use 'GI.Gio.Objects.FileEnumerator.fileEnumeratorClose', or
    -- its asynchronous version, 'GI.Gio.Objects.FileEnumerator.fileEnumeratorCloseAsync'. Once
    -- a t'GI.Gio.Objects.FileEnumerator.FileEnumerator' is closed, no further actions may be performed
    -- on it, and it should be freed with 'GI.GObject.Objects.Object.objectUnref'.

    -- | This is a version of 'GI.Gio.Objects.FileEnumerator.fileEnumeratorNextFile' that\'s easier to
    -- use correctly from C programs.  With 'GI.Gio.Objects.FileEnumerator.fileEnumeratorNextFile',
    -- the gboolean return value signifies \"end of iteration or error\", which
    -- requires allocation of a temporary t'GError'.
    --
    -- In contrast, with this function, a 'P.False' return from
    -- 'GI.Gio.Objects.FileEnumerator.fileEnumeratorIterate' *always* means
    -- \"error\".  End of iteration is signaled by /@outInfo@/ or /@outChild@/ being 'P.Nothing'.
    --
    -- Another crucial difference is that the references for /@outInfo@/ and
    -- /@outChild@/ are owned by /@direnum@/ (they are cached as hidden
    -- properties).  You must not unref them in your own code.  This makes
    -- memory management significantly easier for C code in combination
    -- with loops.
    --
    -- Finally, this function optionally allows retrieving a t'GI.Gio.Interfaces.File.File' as
    -- well.
    --
    -- You must specify at least one of /@outInfo@/ or /@outChild@/.
    --
