A collection of FFI declarations for interfacing with Win32 mapped files.
createFileMapping :: Maybe HANDLE -> ProtectFlags -> DDWORD -> Maybe WindowsString -> IO HANDLE Source
mapFile :: WindowsPath -> 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.
openFileMapping :: FileMapAccess -> BOOL -> Maybe WindowsString -> IO HANDLE Source
| :: WindowsPath | 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.
fILE_SHARE_WRITE :: ShareMode Source
mapViewOfFile :: HANDLE -> FileMapAccess -> DDWORD -> SIZE_T -> IO (Ptr a) Source
mapViewOfFileEx :: HANDLE -> FileMapAccess -> DDWORD -> SIZE_T -> Ptr a -> IO (Ptr b) Source
unmapViewOfFile :: Ptr a -> IO () Source
| :: MappedObject | Mapped object, from withMappedFile |
| -> Integer | Position in file |
| -> Int | Size of mapped area |
| -> (Ptr a -> IO b) | Action |
| -> IO b |
Maps area into memory.
