Message-ID
<7f659603c9ac1457ef581fb82d7fe411bdc7230f.1670882286.git.gitgitgadget@gmail.com>
In-Reply-To
<pull.1352.v5.git.git.1670882286.gitgitgadget@gmail.com>
From: Eric DeCosta <edecosta@mathworks.com>
Linux and Mac OS can share some of the code originally developed for Mac OS.
Mac OS and Linux can share fsm-ipc-unix.c and fsm-settings-unix.c
