### Class

# GioFileEnumerator

#### Description [src]

    class Gio.FileEnumerator : GObject.Object
    {
      /* No available fields */
    }

`GFileEnumerator` allows you to operate on a set of `GFile` objects, returning a `GFileInfo` structure for each file enumerated (e.g. `g_file_enumerate_children()` will return a `GFileEnumerator` for each of the children within a directory).

To get the next file’s information from a `GFileEnumerator`, use `g_file_enumerator_next_file()` or its asynchronous version, `g_file_enumerator_next_files_async()`. Note that the asynchronous version will return a list of `GFileInfo` objects, 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 `g_dir_read_name()`. 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 `GFileEnumerator`, use `g_file_enumerator_close()`, or its asynchronous version, `g_file_enumerator_close_async()`. Once a `GFileEnumerator` is closed, no further actions may be performed on it, and it should be freed with `g_object_unref()`.

#### Ancestors

- GObject

#### Instance methods

###### g_file_enumerator_close

Releases all resources used by this enumerator, making the enumerator return `G_IO_ERROR_CLOSED` on all calls.

###### g_file_enumerator_close_async

Asynchronously closes the file enumerator.

###### g_file_enumerator_close_finish

Finishes closing a file enumerator, started from g_file_enumerator_close_async().

###### g_file_enumerator_get_child

Return a new `GFile` which refers to the file named by `info` in the source directory of `enumerator`. This function is primarily intended to be used inside loops with g_file_enumerator_next_file().

since: 2.36

###### g_file_enumerator_get_container

Get the `GFile` container which is being enumerated.

since: 2.18

###### g_file_enumerator_has_pending

Checks if the file enumerator has pending operations.

###### g_file_enumerator_is_closed

Checks if the file enumerator has been closed.

###### g_file_enumerator_iterate

This is a version of `g_file_enumerator_next_file()` that’s easier to use correctly from C programs. With g_file_enumerator_next_file(), the gboolean return value signifies “end of iteration or error”, which requires allocation of a temporary `GError`.

since: 2.44

###### g_file_enumerator_next_file

Returns information for the next file in the enumerated object. Will block until the information is available. The `GFileInfo` returned from this function will contain attributes that match the attribute string that was passed when the `GFileEnumerator` was created.

###### g_file_enumerator_next_files_async

Request information for a number of files from the enumerator asynchronously. When all I/O for the operation is finished the `callback` will be called with the requested information.

###### g_file_enumerator_next_files_finish

Finishes the asynchronous operation started with g_file_enumerator_next_files_async().

###### g_file_enumerator_set_pending

Sets the file enumerator as having pending operations.

##### Methods inherited from GObject (43)

Please see GObject for a full list of methods.

#### Properties

###### Gio.FileEnumerator:container

The container that is being enumerated.

#### Signals

##### Signals inherited from GObject (1)

###### GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
