DataInputStream.readUint64

Reads an unsigned 64-bit/8-byte value from stream.

In order to get the correct byte order for this read operation, see gio.data_input_stream.DataInputStream.getByteOrder.

If cancellable is not null, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.types.IOErrorEnum.Cancelled will be returned.
