Hi! I'm currently starting to test out lua for my game engine, but I've run into a problem. How can I iterate over all the global variables in a lua_State in C++? Thanks :)

Global variables simply make up a Lua table, one which is located at the lua stack pseudoindex LUA_GLOBALS (that might not be exactly the right name... check the reference manual). So just iterate over that the way you would iterate over any table.

Thanks! I was just not thinking about the fact that I can use the LUA_GLOBALSINDEX directly in the lua_next function, but thought I had to use lua_gettable first :P
