<p>The <strong>ldap_first_entry()</strong> function takes the result from a
call to
<a href="ldap_result.htm">ldap_result()</a>,
<a href="ldap_search_s.htm">ldap_search_s()</a>, or
<a href="ldap_search_st.htm">ldap_search_st()</a>
and returns a pointer to the first entry in the result.</p>
<p>The <strong>ldap_first_entry()</strong>, <a href="ldap_next_entry.htm">
ldap_next_entry()</a>, and <a href="ldap_count_entry.htm">
ldap_count_entries()</a> functions are used to parse results received from
<a href="ldap_result.htm">ldap_result()</a> or the synchronous LDAP search
functions <a href="ldap_search_s.htm">ldap_search_s()</a> and
<a href="ldap_search_st.htm">ldap_search_st()</a>.</p>
<br>
<h3>Authorities and Locks</h3>
<p>No i5/OS authority is required.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong><em>ld</em></strong></dt>
<dd>(Input) The LDAP pointer returned by a previous call to

<a href="ldap_open.htm">ldap_open()</a>.<br><br></dd>
<dt><strong><em>result</em></strong></dt>
<dd>(Input) The result returned by a call to
<a href="ldap_result.htm">ldap_result()</a> or one of the synchronous search routines

<a href="ldap_search_st.htm">ldap_search_st()</a>).</dd>
</dl>
<br>

<dt><strong>NULL</strong></dt>
<dd>if the request was not successful.</dd>
</dl>

<h3>Error Conditions</h3>
<p>If <strong>ldap_first_entry()</strong> is not successful, NULL is returned,
<em>ld_errno</em> will be set to indicate the error. See <a href=
"ldap_error_condt.htm">LDAP Client API Error Conditions</a> for possible LDAP
error code values. Use <a href="ldap_get_errno.htm">ldap_get_errno()</a>
function to retrieve the error information.</p>
