Description
Low level mmap access.
- unsafePackMMapPtr :: Ptr Word8 -> CSize -> IO ByteString
- c_mmap :: CSize -> CInt -> IO (Ptr Word8)
- c_munmap :: Ptr Word8 -> CSize -> IO CInt
Converting an mmapped pointer to a ByteString
unsafePackMMapPtr :: Ptr Word8 -> CSize -> IO ByteString
Create a bytestring from a memory mapped Ptr. A finalizer will be associated with the resource, that will call munmap when the storage manager detects that the resource is no longer in use.
Low level bindings
