Initialize a new FileEnumerator.

Returns the type id (GType) registered in GLib type system.

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().

To use this, %G_FILE_ATTRIBUTE_STANDARD_NAME must have been listed in the attributes list used when creating the #GFileEnumerator.

This is a convenience method that's equivalent to: |[ gchar *name = g_file_info_get_name (info); GFile *child = g_file_get_child (g_file_enumerator_get_container (enumr), name); ]|

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

This will be automatically called when the last reference is dropped, but you might want to call this function to make sure resources are released as early as possible.

Asynchronously closes the file enumerator.

If @cancellable is not nil, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error %G_IO_ERROR_CANCELLED will be returned in g_file_enumerator_close_finish().

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

If the file enumerator was already closed when g_file_enumerator_close_async() was called, then this function will report %G_IO_ERROR_CLOSED in @error, and return false. If the file enumerator had pending operation when the close operation was started, then this function will report %G_IO_ERROR_PENDING, and return false. If @cancellable was not nil, then the operation may have been cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error %G_IO_ERROR_CANCELLED will be set, and false will be returned.

Get the #GFile container which is being enumerated.

Checks if the file enumerator has pending operations.

Checks if the file enumerator has been closed.

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.

In contrast, with this function, a false return from g_file_enumerator_iterate() always means "error". End of iteration is signaled by @out_info or @out_child being nil.

Another crucial difference is that the references for @out_info and @out_child 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 #GFile as well.

You must specify at least one of @out_info or @out_child.

The code pattern for correctly using g_file_enumerator_iterate() from C is:

|[ direnum = g_file_enumerate_children (file, ...); while (TRUE) { GFileInfo *info; if (!g_file_enumerator_iterate (direnum, &info, NULL, cancellable, error)) goto out; if (!info) break; ... do stuff with "info"; do not unref it! ... }

out: g_object_unref (direnum); // Note: frees the last @info ]|

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.

See the documentation of #GFileEnumerator for information about the order of returned files.

On error, returns nil and sets @error to the error. If the enumerator is at the end, nil will be returned and @error will be unset.

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.

See the documentation of #GFileEnumerator for information about the order of returned files.

The callback can be called with less than @num_files files in case of error or at the end of the enumerator. In case of a partial error the callback will be called with any succeeding items and no error, and on the next request the error will be reported. If a request is cancelled the callback will be called with %G_IO_ERROR_CANCELLED.

During an async request no other sync and async calls are allowed, and will result in %G_IO_ERROR_PENDING errors.

Any outstanding i/o request with higher priority (lower numerical value) will be executed before an outstanding request with lower priority. Default priority is %G_PRIORITY_DEFAULT.

Finishes the asynchronous operation started with g_file_enumerator_next_files_async().

Sets the file enumerator as having pending operations.
