Simple Region Allocator

Basic region / stack allocator for your C and C++ projects.

Using the Library

Include region.h in every file that it's needed. Make sure to include #define IMPLEMENT_REGIONS before including region.h in your entrypoint. If you need access to debug functions, you can also include #define DEBUG_REGIONS in your entrypoint.

Regions are 1MB in size by default; you can redefine REGION_SIZE or use a multiplier as desired to change the allocation size. See main.c included in this repository for an example implementation.

Included Demo

Type make test to see the included example in action, which allocates 4GiB of structures and prints some debug information about memory usage.

You can also modify the parameters by providing the arenas binary with some additional arguments, as follows:

./arenas [ENABLE_DEBUG_PRINTING] \
         [NUMBER_OF_THREADS]     \
         [OBJECT_MULTIPLIER]     \
         [REGION_SIZE]           \
         [VISUAL_SCALE]
