How would I make a C-function that I can call from Lua? -

-

i know how make c-function , able tell lua it, call lua. have lua libraries installed on mac osx 10.4 computer.

there's excellent example of lua-c integration here , here.

if need export function global namespace, then:

  1. declare function (let's call f) signature lua_cfunction.
  2. call lua_register(l, "myfunc", f), l being lua state, , function = f.
  3. run lua code. f available in global namespace myfunc.

if you're going use stock interpreter might want make library. this guy wrote article lua programming gems explains how it. sources available online.
