using lua - off topic

hi.. i know its a little off topic.. but i wanted to use your lua port in another project.. but i dont know where to link lua into my app so i can call lua scripts that can then control obj-c/C functions

AFAIK, SIO2 doesn't use any specific Lua "port", it's just the plain vanilla Lua source (pure C like SIO2, too) together with a generated binding for the SIO2 API. The latter would be exactly the place to look how to make C functions available in Lua.

Best,
Matt
