Reading and writing

processVMReadV :: CPid -> Ptr Word8 -> Int -> IO [Word8] Source #

Wrapper function for process_vm_readv. No flags, only single io vectors are read

processVMWriteV :: CPid -> Ptr Word8 -> Int -> [Word8] -> IO () Source #

Wrapper function for process_vm_writev. No flags, only single io vectors are written

encode :: Binary a => a -> [Word8] Source #

Wrapper function for Data.Binary.encode. Our package works with lists of Word8 so this is a convenient helper function that does the conversion for you.

It is not efficient, but this module is not designed for large amounts of memory transfers anyway.

decode :: Binary a => [Word8] -> a Source #
