From 9b4c1ce9f6e79cf3194b3777813365a623688c47 Mon Sep 17 00:00:00 2001 From: Quincey Koziol Date: Tue, 17 May 2005 14:01:07 -0500 Subject: [svn-r10750] Purpose: New feature. Description: Add "memory pool" internal data structure. This set of routines is designed to add a way to allocate small pieces of information for a particular purpose and then free all the pieces at once (i.e. without having to free each piece individually). Memory pools are also good for localizing lots of small allocations that logically belong together. For example, if you were constructing a temporary linked list, you could create a new memory pool, allocate all the nodes for the list from the memory pool and when you were done with the list, just destroy the pool instead of tracking through the list and freeing each block independently.
