mapFile :: FilePath -> IO (ForeignPtr a, Int) Source #
Maps file fully and returns ForeignPtr and length of the mapped area. The mapped file is opened read-only and shared reading.
mapFile :: FilePath -> IO (ForeignPtr a, Int) Source #
Maps file fully and returns ForeignPtr and length of the mapped area. The mapped file is opened read-only and shared reading.
data MappedObject Source #
Constructors
| MappedObject HANDLE HANDLE FileMapAccess |
Arguments
| :: FilePath | Path |
| -> Bool | Write? (False = read-only) |
| -> Maybe Bool | Sharing mode, no sharing, share read, share read+write |
| -> (Integer -> MappedObject -> IO a) | Action |
| -> IO a |
Opens an existing file and creates mapping object to it.
Arguments
