<h2>External Data Representation APIs</h2>

<p>The eXternal Data Representation (XDR) functions define a uniform way to
|
||
|
|
represent data types and define a language that can describe data structures of
|
||
|
|
arbitrary complexity in a standard way.</p>
|
||
|
|
|
||
|
|
<p>All XDR APIs can translate data in two directions:</p>
