From 2dd5f4cce61f95468cd84d7272b8c455d0b6408b Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 26 Jan 2016 09:01:14 -0600 Subject: [PATCH] cbfstool: provide buffer_offset() Instead of people open coding the offset field access within a struct buffer provide buffer_offset() so that the implementation can change if needed without high touch in the code base.
