<hr><h2>Detailed Description</h2>
Regional allocator.
<p>
Allocates small portions of of larger chunks. Based on region-allocator from NSD, but rewritten to be light.<p>
Different from (nsd) region-allocator.h o does not have recycle bin o does not collect stats; just enough to answer get_mem() in use. o does not keep cleanup list o does not have function pointers to setup o allocs the <a class="el" href="structregional.html" title="the regional* is the first block*.">regional</a> struct inside the first block. o can take a block to create <a class="el" href="structregional.html" title="the regional* is the first block*.">regional</a> from. o blocks and large allocations are kept on singly linked lists. <hr><h2>Function Documentation</h2>
