<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>

<h3>Parameters</h3>
|
|
|
|
<dl>

<br>
|
|
</dd>
|
|
|
|
<dt><strong>cred_handle</strong> (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> (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> (Output)</dt>
|
|
|
|
<dd>The number of seconds for which the credential remains valid. The returned

this parameter if the credential lifetime is not required.<br>

|
|
</dd>
|
|
|
|
<dt><strong>cred_usage</strong> (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>

<dt><strong>mechanisms</strong> (Output)</dt>
|
|
|
|
<dd>The set of security mechanisms supported by the credential. Specify

<h3>Return Value</h3>
|

|
<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>

<dt><strong>GSS_S_FAILURE</strong></dt>
|
|
|
|
<dd>The routine failed for reasons that are not defined at the GSS level. The
