-> Int

length in bytes

-> String

user beware, no checks are made

toHexadecimal

Arguments

:: Ptr Word8

destination memory

-> Ptr Word8

source memory

-> Int

number of bytes

-> IO ()

Transform a number of bytes pointed by.src in the hexadecimal binary representation in dst

destination memory need to be of correct size, otherwise it will lead to really bad things.

fromHexadecimal :: Ptr Word8 -> Ptr Word8 -> Int -> IO (Maybe Int)
