Gio.FileIOStream.prototype.query_info_async

function query_info_async(attributes: String, io_priority: Number(gint), cancellable: Gio.Cancellable, callback: Gio.AsyncReadyCallback): void {
    // Gjs wrapper for g_file_io_stream_query_info_async()
}
  

Asynchronously queries the stream for a Gio.FileInfo. When completed, callback will be called with a Gio.AsyncResult which can be used to finish the operation with Gio.FileIOStream.prototype.query_info_finish.

For the synchronous version of this function, see Gio.FileIOStream.prototype.query_info.
