<p>The <strong>gss_inquire_cred()</strong> function returns information about a
GSS credential to the calling application. If
<strong>GSS_C_NO_CREDENTIAL</strong> is specified for the <em>cred_handle</em>
parameter, the default security mechanism is used to process the request.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong>minor_status</strong>&nbsp;&nbsp;(Output)</dt>
<dd>A status code from the security mechanism.<br>
<br>
</dd>
<dt><strong>cred_handle</strong>&nbsp;&nbsp;(Input)</dt>
<dd>The handle for the GSS credential. Specify
<strong>GSS_C_NO_CREDENTIAL</strong> to get information about the default
credential for the default security mechanism.<br>
<br>
</dd>
<dt><strong>name</strong>&nbsp;&nbsp;(Output)</dt>
<dd>The principal name associated with the credential. Specify
<strong>NULL</strong> for this parameter if the principal name is not
required.<br>
<br>
</dd>
<dt><strong>lifetime</strong>&nbsp;&nbsp;(Output)</dt>
<dd>The number of seconds for which the credential remains valid. The returned
value is zero if the credential has expired. Specify <strong>NULL</strong> for
this parameter if the credential lifetime is not required.<br>
<br>
</dd>
<dt><strong>cred_usage</strong>&nbsp;&nbsp;(Output)</dt>
<dd>One of the following values describing how the application can use the
credential. Specify <strong>NULL</strong> for this parameter if the credential
usage is not required.<br>
<br>
<table cellpadding="5">
<!-- cols="15 85" -->
<tr>
<td align="left" valign="top" nowrap><em>GSS_C_INITIATE</em></td>
<td align="left" valign="top">The application may initiate a security
context.</td>
</tr>
<tr>
<td align="left" valign="top"><em>GSS_C_ACCEPT</em></td>
<td align="left" valign="top">The application may accept a security
context.</td>
</tr>
<tr>
<td align="left" valign="top"><em>GSS_C_BOTH</em></td>
<td align="left" valign="top">The application may both initiate and accept
security contexts.</td>
</tr>
</table>
<br>
<br>
</dd>
<dt><strong>mechanisms</strong>&nbsp;&nbsp;(Output)</dt>
<dd>The set of security mechanisms supported by the credential. Specify
<strong>NULL</strong> for this parameter if the mechanism set is not required.
The gss_OID_set returned for this parameter should be released when it is no
longer needed by calling the <strong>gss_release_oid_set()</strong>
routine.</dd>
</dl>
<br>
<h3>Return Value</h3>
<p>The return value is one of the following status codes:</p>
<dl>
<dt><strong>GSS_S_COMPLETE</strong></dt>
<dd>The routine completed successfully.<br>
<br>
</dd>
<dt><strong>GSS_S_CREDENTIALS_EXPIRED</strong></dt>
<dd>The credentials have expired. Credential information is still returned for
an expired credential, but the <em>lifetime</em> value is returned as zero.<br>
<br>
</dd>
<dt><strong>GSS_S_DEFECTIVE_CREDENTIAL</strong></dt>
<dd>The credentials are not valid.<br>
<br>
</dd>
<dt><strong>GSS_S_FAILURE</strong></dt>
<dd>The routine failed for reasons that are not defined at the GSS level. The
<em>minor_status</em> return parameter contains a mechanism-dependent error
code describing the reason for the failure.<br>
<br>
</dd>
<dt><strong>GSS_S_NO_CRED</strong></dt>
<dd>The <em>cred_handle</em> parameter does not refer to a valid credential or
there are no default credentials available.<br>
<br>
</dd>
</dl>
