Getting the callers environment in c

[Chris Gagnon <cgagnon@...>]

Lets say i have some lua that calls SomeFunc() which I've mapped to SomeFuncImplementation()

All my lua runs in environments that contain an ID.

here is the c:

int SomeFuncImplementation(lua_State * L)

{

   // I need the ID

   // How do i get it!?

   // This doesn't work because it's the environment of this c function which is useless to me

   lua_getfield(L, "ID", LUA_ENVIRONINDEX);

  // lua_getfenv() is useless cause i can't get the calling function on the stack to use this

}

It's seems like this should be easy, what am i missing?
