Objectives

Create a ring fifo for accessing chunk buffer directly so that don't need memory copy.

How to build

make -C src

How to use

You will get static library (librfifo.a) after build successfully. And then include rfifo.h by your C file and link with static file directly. You can reference the sample code: test_rfifo.c

run tests

make -C src tests

example file

./test_rfifo
