/**
* g_file_replace_contents_bytes_async:
* @file: input #GFile
* @contents: a #GBytes
* @etag: (allow-none): a new <link linkend="gfile-etag">entity tag</link> for the @file, or %NULL
* @make_backup: %TRUE if a backup should be created
* @flags: a set of #GFileCreateFlags
* @cancellable: optional #GCancellable object, %NULL to ignore
* @callback: a #GAsyncReadyCallback to call when the request is satisfied
* @user_data: the data to pass to callback function
*
* Same as g_file_replace_contents_async() but takes a #GBytes input instead.
* This function will keep a ref on @contents until the operation is done.
* Unlike g_file_replace_contents_async() this allows forgetting about the
* content without waiting for the callback.
*
* When this operation has completed, @callback will be called with
* @user_user data, and the operation can be finalized with
* g_file_replace_contents_finish().
*
* Since: 2.40
