In factthe RFC declares the return to be of type <tt>unsigned short</tt> and specifiesthat (negative) <a href="SLPError.html">SLPError</a> codes are returnedon error. Since a negative return could also be interpreted as (avery large) unsigned value, OpenSLP does not return <a href="SLPError.html">SLPError</a>codes cast to unsigned shorts it just returns zero.<h3>See Also</h3><a href="SLPReg.html">SLPReg()</a></body></html>⌨️ 快捷键说明
