<h3>Summary</h3>
|
||
|
||
<p><code>mod_slotmem</code> provides an interface to a
|
||
memory allocation implementation which is based on the
|
||
concept of datasets being in various "slots" within
|
||
a larger memory segment. As such, it is similar in
|
||
concept to a generic table or array. The real use of
|
||
the module is as a front-end to various providers
|
||
(such as <code class="module"><a href="../mod/mod_sharedmem.html">mod_sharedmem</a></code>) which deal
|
||
with the actual implementations. This allows modules
|
||
to use a single API for memory usage, to matter what
|
||
the underlying implementation is.
|
||
</p>
|
||
|
||
<p><code>mod_slotmem</code> provides the following
|
||
API functions:
