Nmap Development: Re: [NSE patch] patch for pack/unpack to use platform independant types

["Philip Pickering" <pgpickering () gmail com>]

Hi!

Just another problem I was working on the last few days:

local l = bin.pack(">L", 18446740000000000000)
print(bin.unpack("H" .. #l, l))

prints on windows:
9       8000000000000000

instead of
9       FFFFFC4B83FD4000
(as it does on Linux)


Even when I typecast the lua_Number (which is
a double) to an unsigned __int64 directly in
luaL_checknumber and print it, it is exactly 2^63.

Does anyone have a clue?

Philip
