how to create object with given names

["Jiangwei Li" <jli@...>]

hi, 

i am new to lua, and want to use it in my project.
however, i got a question as following:

i would like to create objects in C 
based on names specified in the script table. 

for example:

I have a c data structure 

typedef Point_s {
  int x, y
} Point_t;

In script, I have a table:
PointsToBeCreated = {
  east="1,0",
  north="0, 1",
}

In c, I want to create two objects
of type Point_t, one called
"east" and one called "north", based
on what is given in the 
table "PointsToBeCreated".

So, later, in the script, i can say:

setPosition = function ()
  local a = east   -- note: east is auto created
  ...
  ...
end

can anyone please tell me 
how to do the this using lua c api?

thanks and best regards,
