On lua function return how to determine return value

[Austin Einter <austin.einter@...>]

Hi All

Lets say I called lua function from C code.

Say Lua function returned 1 integer, 1 double and 1 string.

To check the type I am using below code. Looks for integer and double the type is LUA_TNUMBER. How to distinguish if the return value is integer or double.

      int i;
      int top = lua_gettop(L);
      for (i = 1; i <= top; i++) {  /* repeat for each level */
        int t = lua_type(L, i);
        switch (t) {
    
          case LUA_TSTRING:  /* strings */
            printf("`%s'", lua_tostring(L, i));
            break;
    
          case LUA_TBOOLEAN:  /* booleans */
            printf(lua_toboolean(L, i) ? "true" : "false");
            break;
    
          case LUA_TNUMBER:  /* numbers */
            printf("%g", lua_tonumber(L, i));
            break;
    
          default:  /* other values */
            printf("%s", lua_typename(L, t));
            break;
    
        }
        printf("  ");  /* put a separator */
      }

Thanks
