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, although some, most notably float and double are
only supported on those operating systems that provide an XDR
library.
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.
