#include &lt;qsyvldl.h&gt;

<p>The <strong>QsyFindValidationLstEntry()</strong> function finds an entry in
a validation list object. The function then returns the information for the
entry in the buffer that is pointed to by the <em>Rtn_Entry</em> parameter. To
find an entry, there must be an exact match in the entry for the value that is
specified in the <em>Entry_ID</em> parameter and the length of the entry ID.
For example, an entry ID value of "SMITH" with a length of 5 would not find an
entry where the entry ID is "SMITH " and the length is 7.<br>

<p><strong>Note:</strong> If the QsyEncryptData attribute is set to
QSY_VFY_FIND_E (1), then the user must have *USE, *ADD, and *UPD authority to
the validation list to get the data to be encrypted returned in the
<em>Rtn_Entry</em> parameter.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong>Validation_Lst</strong></dt>
<dd>(Input)
<p>A pointer to the qualified object name of the validation list in which to
find the entry. The first 10 characters specify the validation list name, and
the second 10 characters specify the library. You can use these special values
for the library name:</p>
<table cellpadding="5">
<!-- cols="15 85" -->

<td align="left" valign="top"><em>*CURLIB</em></td>
<td align="left" valign="top">The current library is used to locate the
validation list. If there is no current library, QGPL (general purpose library)
is used.</td>

list.</td>
</tr>
</table>
<br>
</dd>
<dt><strong><a name="entry_id">Entry_ID</a></strong></dt>
<dd>(Input)
<p>A pointer to the entry ID information. The format of the Qsy_Entry_ID_Info_T
structure is as follows:</p>
<table border cellpadding="5">
<!-- cols="15 20 65" -->
<tr>
<td align="left" valign="top">int</td>
<td align="left" valign="top">Entry_ID_Len</td>

</dd>
<dt><strong>Rtn_Entry</strong></dt>
<dd>(Output)
<p>A pointer to the buffer where the entry information is placed. The buffer
must be allocated to the size of the <em>Qsy_Rtn_Vld_Lst_Ent_T</em> structure
or the results will be unpredictable. The format of the
<em>Qsy_Rtn_Vld_Lst_Ent_T</em> structure is as follows:</p>
