basic memory node structure <dl compact><dt><b>Note:</b></dt><dd>The next, ref and first_avail fields are available for use by the caller of <a class="el" href="group__apr__allocator.html#g1faf4ae0fdffe952b0a80d272ab02654">apr_allocator_alloc()</a>, the remaining fields are read-only. The next field has to be used with caution and sensibly set when the memnode is passed back to <a class="el" href="group__apr__allocator.html#gbe55fa0b1926a78576341e323172d08c">apr_allocator_free()</a>. See <a class="el" href="group__apr__allocator.html#gbe55fa0b1926a78576341e323172d08c">apr_allocator_free()</a> for details. The ref and first_avail fields will be properly restored by <a class="el" href="group__apr__allocator.html#gbe55fa0b1926a78576341e323172d08c">apr_allocator_free()</a>. </dd></dl>
