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.
