Iterating over a table from C

[Philip Pemberton <lists@...>]

Hi guys,

Does anyone know if it's possible to iterate over the contents of a
table from C?

I'm creating something similar to the configuration file example in
"Programming In Lua" 2ed. For instance, given this table (stored as a
global variable):

  shapes = {
    one = {
      colour = 'red'
      shape = 'round'
    }
    two = {
      colour = 'blue'
      shape = 'triangle
    }
  }

I want to make my C code iterate over 'one' and 'two'. In Lua it's
fairly simple --
  for x in shapes do
    print "A " .. shapes[x]['colour'] .. " " .. shapes[x]['shape']
  end

(I suspect I've hammed the syntax a bit, but you get the idea)

How can I do this in C?

Thanks,

Phil.
