SLPClose</h2>

<hr WIDTH="100%">
<h3>
Declaration</h3>
<tt>#include &lt;slp.h></tt>
<p><tt>void SLPClose(<a href="SLPTypes.html#SLPHandle">SLPHandle</a> <a href="#hslp">hslp</a>)</tt>
<br>&nbsp;
<h3>
Description</h3>
Frees all resources associated with the handle.&nbsp; If the handle was
invalid, the functions returns silently.&nbsp; Any outstanding synchronous
or asynchronous operations are canceled so their callback functions will
not be called any longer.
<p>In the OpenSLP implementation, SLPHandles are used to cache information
that is costly to obtain (in terms of network usage and time).&nbsp;&nbsp;
Since the RFC 2614 API does not provide function calls to for library initialization,&nbsp;
OpenSLP keeps track of the number of SLPHandles that are open.&nbsp;&nbsp;
Several global library data structures are initialized when the first SLPHandle
is opened and maintained until the last SLPHandle is closed.&nbsp; Therefore,
it is most efficient to leave SLPHandles open for as long as you will need
them (often for the entire life of a process).&nbsp;&nbsp;&nbsp; If you
can help it, DO NOT make a habit of opening and closing SLPHandles frequently.
