Re: [Haskell-cafe] Re: "C" buffer suggestions??

See the Data.ByteString.Internal docs: http://www.haskell.org/ghc/docs/latest/html/libraries/bytestring/Data-ByteSt... Of course, you'd better not write to the contents of that pointer, or bad things could happen... David On Mon, Jun 23, 2008 at 08:18:23PM -0500, Galchin, Vasili wrote:

e.g. on Word8 .....

let aiocb = AIOCB{ aioFd=fd, aioLioOpcode=0, aioReqPrio=0, aioOffset=0, aioBuf=??, <<<<<<<<<<<<<<<<<<<<< Ptr Word8 aioBytes=128, aioSigevent=event}

ok .....

1) how do I marshall from ByteString to char * (poke)??

2) how do I write

let x =??? :: Word8

3) how do I write

let y = ??? ::ByteString

Kind regards, Vasili

So heap allocated and collected, but not moved.

My bad. In that case, you might want to work with ByteStrings all the way since it might make building the visible interface (which probably should use ByteStrings) easier.
