greetings,
i am creating broadcast addresses. is there such a function in an erlang
module? my current solution is:
broadcast_address( Address, Mask ) ->
Fun = fun ( Int ) -> 255 bxor Int end,
Inverted = lists:map( Fun, Mask ),
lists:zipwith( fun erlang:'bor'/2, Address, Inverted ).
is there a better way?
if somebody asks me about where the bit operators/functions are
documented, where should i tell them to look? it is not in the erlang
module (or have i just missed them). there is no ''bnot'' in the
permuted index (actually there is not even a ''bif'' in the permuted
index). ''bnot'' seems to operate on signed integers. i would like to
invert an unsigned char.
