<h2>ldap_explode_dn()--Break a Distinguished Name into Its Components</h2>
<div class="box" style="width: 70%;">

&nbsp;&nbsp;Syntax<br>
<pre>
#include &lt;ldap.h&gt;
char **ldap_explode_dn(
const char *<em>dn</em>,
int <em>notypes</em>)
</pre>

<p>The <strong>ldap_explode_dn()</strong> function uses the distinguished name
in local codepage returned by <a href="ldap_get_dn.htm">ldap_get_dn()</a> and
breaks it up into its component parts. Each part is known as a Relative
Distinguished Name (RDN). If the dn is in UTF8, use <a href=
"ldap_explode_dn_utf8.htm">ldap_explode_dn_utf8()</a>.</p>
<p><strong>ldap_explode_dn()</strong> returns a NULL-terminated array, each
component of which contains an RDN from the DN. The <em>notypes</em> parameter
is used to request that only the RDN values be returned, not their types.</p>
<p>For example, the distinguished name cn=Bob,c=US would return as either
"cn=Bob","c=US",NULL or "Bob","US", NULL depending on whether <em>notypes</em>
was 0 or 1, respectively. The result can be freed by calling <a href=
"ldap_value_free.htm">ldap_value_free()</a>.</p>
<br>
<h3>Authorities and Locks</h3>
<p>No i5/OS authority is required.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><em>dn</em></dt>
<dd>(Input) Specifies the DN to be exploded (as returned from <a href=
"ldap_get_dn.htm">ldap_get_dn()</a>).</dd>
<dt><em>notypes</em></dt>
<dd>(Input) Specifies if type information is to be returned with each RDN. If
non-zero, the type information will be stripped. If zero, the type information
is retained. For example, setting <em>notypes</em> to 1 would result in the RDN
"cn=Fido" being returned as "Fido".</dd>
</dl>
<br>
<h3>Return Value</h3>
<dl>
<dt><strong>Relative Distinguished Name (RDN)</strong></dt>
<dd>if the request was successful.<br>
<br>
</dd>
<dt><strong>NULL</strong></dt>
<dd>if the request was not successful.</dd>
</dl>
<br>
<h3>Error Conditions</h3>
<p>If <strong>ldap_explode_dn()</strong> is not successful, then there was no
memory available for either the array or its component parts.</p>
