---- importing ---- require('example') -- First create some objects using the pointer library. print("Testing the pointer library") a = example.new_intp() b = example.new_intp() c = example.new_intp() example.intp_assign(a,37) example.intp_assign(b,42) print(" a = "..tostring(a)) print(" b = "..tostring(b)) print(" c = "..tostring(c)) -- Call the add() function with some pointers example.add(a,b,c) -- Now get the result r = example.intp_value(c) print(" 37 + 42 = "..r) -- Clean up the pointers -- since this is C-style pointers you must clean it up example.delete_intp(a) example.delete_intp(b) example.delete_intp(c) -- Now try the typemap library -- This should be much easier. Now how it is no longer -- necessary to manufacture pointers. print("Trying the typemap library") r = example.sub(37,42) print(" 37 - 42 = "..r) -- Now try the version with multiple return values print("Testing multiple return values") q,r = example.divide(42,37) print(" 42/37 = "..q.." remainder "..r)
