<h3>
|
|
Description</h3>
|
|
Frees all resources associated with the handle. If the handle was
|
|
invalid, the functions returns silently. 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).
|
|
Since the RFC 2614 API does not provide function calls to for library initialization,
|
|
OpenSLP keeps track of the number of SLPHandles that are open.
|
|
Several global library data structures are initialized when the first SLPHandle
|
|
is opened and maintained until the last SLPHandle is closed. 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). If you
|
|
can help it, DO NOT make a habit of opening and closing SLPHandles frequently.
