<p>This function performs the client side of a sendauth/recvauth exchange by sending and receiving messages over <em>fd</em> .</p>
<p>Credentials may be specified in three ways:</p>
<blockquote>
<div><blockquote>
<div><ul class="simple">
<li>If <em>in_creds</em> is NULL, credentials are obtained with <a class="reference internal" href="krb5_get_credentials.html#c.krb5_get_credentials" title="krb5_get_credentials"><tt class="xref c c-func docutils literal"><span class="pre">krb5_get_credentials()</span></tt></a> using the principals <em>client</em> and <em>server</em> . <em>server</em> must be non-null; <em>client</em> may NULL to use the default principal of <em>ccache</em> .</li>
<li>If <em>in_creds</em> is non-null, but does not contain a ticket, credentials for the exchange are obtained with <a class="reference internal" href="krb5_get_credentials.html#c.krb5_get_credentials" title="krb5_get_credentials"><tt class="xref c c-func docutils literal"><span class="pre">krb5_get_credentials()</span></tt></a> using <em>in_creds</em> . In this case, the values of <em>client</em> and <em>server</em> are unused.</li>
<li>If <em>in_creds</em> is a complete credentials structure, it used directly. In this case, the values of <em>client</em> , <em>server</em> , and <em>ccache</em> are unused.</li>
</ul>
</div></blockquote>
<p>If the server is using a different application protocol than that specified in <em>appl_version</em> , an error will be returned.</p>
</div></blockquote>
