Well, this is not the final/perfect solution, but it is simpler:
ensure that signal(2,1) is first called, then this will do the job:
local res = io.read()
if not res then
print 'ctrl-c caught'
return ''
end
where signal() is declared like this
require 'alien'
local lib = alien.load 'msvcrt.dll' -- or alien.default for Unix
signal = lib.signal
signal:types{ret='int','int','int'}
