Other people have actually answered your question, but you may want to
consider adopting a slightly different approach: instead of parsing your
data structure from C, you could instead parse it from Lua and inform
your C code of the data it needs that way. This might make the code
easier to handle. So either:

for index, o in ipairs(applications) do
  inform_c_of_application_type(index, o.type)
end

...or:

function GetApplicationType(i)
  return applications[i].type
end

...depending on whether you want C or Lua to own the data structures.
Either way, putting the messy bits of the code in Lua might be easier
and more reliable than trying to do it in C --- performance isn't an
issue, right?
