<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<p>Token routines using fread and fwrite. </p>
<p>Additional code has been added to detect tokens which are sent without a length field. These can currently be only SSL tokens. This does require some knowledge of the underlying GSSAPI, by the application, but is within the guidelines of the GSSAPI specifications.</p>
<p>The get routine will automaticly attempt this test, while a new send routine will check a flag. The old send routine will work as before, sending a 4-byte length. </p>
