# 11.17 Standard Module `xdrlib`

The `xdrlib` module supports the External Data Representation Standard as described in RFC 1014, written by Sun Microsystems, Inc. June 1987. It supports most of the data types described in the RFC.

The `xdrlib` module defines two classes, one for packing variables into XDR representation, and another for unpacking from XDR representation. There are also two exception classes.

- 11.17.1 Packer Objects
- 11.17.2 Unpacker Objects
- 11.17.3 Exceptions
