5.0 changes question

[Brian Hook <hook_l@...>]

I haven't used the C API much, so putting in Lua5 has caused some 
problems that I'm leery of just blithely "fixing".

The first is that lua_getn() has gone away -- what's the proper 
replacement?

The second is that lua_getglobals() now requires a second parameter 
"idx", what should I use to get the same behaviour as the old 
lua_getglobals()?

Thanks,

Brian
