 663 <p>libmemcached(3) allows you to specify your own memory allocators, optimized
 664 for your application. This enables libmemcached to be used inside of applications that have their own malloc implementation.</p>
 665 <p><a class="reference internal" href="#c.memcached_set_memory_allocators" title="memcached_set_memory_allocators"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_set_memory_allocators()</span></code></a> is used to set the memory
 666 allocators used by the memcached instance specified by ptr. Please note that
 667 you cannot override only one of the memory allocators, you have to specify a
 668 complete new set if you want to override one of them. All of the memory
 669 allocation functions should behave as specified in the C99 standard. Specify
 670 NULL as all functions to reset them to the default values.</p>
 671 <p><a class="reference internal" href="#c.memcached_get_memory_allocators" title="memcached_get_memory_allocators"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_get_memory_allocators()</span></code></a> is used to get the currently used
 672 memory allocators by a memcached handle.</p>
 673 <p><a class="reference internal" href="#c.memcached_get_memory_allocators_context" title="memcached_get_memory_allocators_context"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_get_memory_allocators_context()</span></code></a> returns the void * that
 674 was passed in during the call to <a class="reference internal" href="#c.memcached_set_memory_allocators" title="memcached_set_memory_allocators"><code class="xref c c-func docutils literal notranslate"><span class="pre">memcached_set_memory_allocators()</span></code></a>.</p>
 675 <p>The first argument to the memory allocator functions is a pointer to a
 676 memcached structure, the is passed as const and you will need to clone
 677 it in order to make use of any operation which would modify it.</p>

 680 <h2>NOTES<a class="headerlink" href="#notes" title="Permalink to this headline">¶</a></h2>
 681 <p>In version 0.38 all functions were modified to have a context void pointer
 682 passed to them. This was so that customer allocators could have their
 683 own space for memory.</p>
