int <b>websDecode64</b>(char_t *outbuf, char_t *string, int outlen);
</pre>

<h2>Parameters</h2>
<p><table width=90% border=0>
    <TR>
        <TD width=40>outbuf</TD>
        <TD>Output buffer</TD>
    </TR>
    <TR>

<h2>Description</h2>

<P>The websDecode64 procedure decodes the <EM>string</EM> 
argument into the supplied <EM>outbuf</EM> buffer. websDecode64 can decode 
in-situ. Ie. <EM>outbuf</EM> and <EM>string</EM>       
             
          
  can be 
the same.&nbsp; </P>

<h2>Return Value</h2>
<p>       Returns 0 if successful. Returns -1 if the 
<EM>string</EM> was not a valid base 64 encoded       string.</p>

<h2>Example</h2>
<pre>
websEncode64(encoded, &quot;String with special characters \&quot; %&quot;, 
    sizeof(encoded));
websDecode64(decoded, encoded, sizeof(decoded));
</pre>
