How to access nested Lua tables from C -

-

Assume that I want to set a value (such as function) inside the nested table with lava-c API. 

  - lua.lua glob = {nest = {- set value here}}

How do I set up a heap to reach the inner table?

Is it just calling gettable many times and then a settop , like in the following code? 

  Lua_pushstring (state, "globe"); Lua_gettable (state, -1); Lua_pushstring (state, "nest"); Lua_gettable (state, -1); Lua_pushcclosure (state, and func, 0); Lua_settop (state, "fun"); Lu_pop (state, 2);    
 
 
 This code sets  glob.nest.name  C function: 
 
  lua_glockGlobal (state, "globe"); Lua_getfield (state, -1, "nest"); Lua_pushcclosure (state, and func, 0); Lua_setfield (state, -1, "name"); To add other fields to   
  glob.nest , just keep going: 
 
  ... lua_pushcclosure (state, &) ; Second, 0); Lua_setfield (state, -1, "second name");
