<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>A process must have the <samp>*iosyscfg</samp> special authority to use
|
||
|
|
<em>setdomainname()</em>.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>The name of the domain is set to NULL when the pointer to the domain name
|
||
|
|
(pointed to by the <em>name</em> parameter) is set to NULL.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li><em>setdomainname()</em> only allows domain names that are made up of
|
||
|
|
invariant characters. In addition, the domain name is assumed to be in the
|
||
|
|
default coded character set identifier (CCSID) currently in effect for the job.
|
||
|
|
|
||
|
|
|
||
|
|
<p><strong>Note:</strong> For exceptions to the invariant character set for
|
||
|
|
some CCSIDs, see <a href="../nls/rbagsglobalmain.htm">globalization</a>
|
||
|
|
topic.</p>
