From 1d73b52f5ba4184de6acf474f14668001304a10c Mon Sep 17 00:00:00 2001 From: David Barr Date: Mon, 9 Aug 2010 17:34:42 -0500 Subject: Add string-specific memory pool Intern strings so they can be compared by address and stored without wasting space. This library uses the macros in the obj_pool.h and trp.h to create a memory pool for strings and expose an API for handling them.
