Hi Everyone,
I was embedding Lua into an RTOS and needed to add my own user
libraries. I decided to modify linit.c to allow me to hook in another
set of libraries. My question is, what would be the best way to add your
own libraries as I can not dynamically load the libraries. I have
attached my modified version of linit.c in hopes you can enlighten me on
a better method.
Thanks
