newtype SOName a

Reference to a shared object; can be sent to other processes.

Constructors

SOName (ForeignPtr CChar)

Instances

Eq (SOName a)

Defined in Foreign.SharedObjectName.Internal

Methods

(==) :: SOName a -> SOName a -> Bool

(/=) :: SOName a -> SOName a -> Bool

Ord (SOName a)

Defined in Foreign.SharedObjectName.Internal

Methods

compare :: SOName a -> SOName a -> Ordering

(<) :: SOName a -> SOName a -> Bool

(<=) :: SOName a -> SOName a -> Bool

(>) :: SOName a -> SOName a -> Bool

(>=) :: SOName a -> SOName a -> Bool

max :: SOName a -> SOName a -> SOName a

min :: SOName a -> SOName a -> SOName a

Read (SOName a)

Defined in Foreign.SharedObjectName.Internal

Methods

readsPrec :: Int -> ReadS (SOName a)

readList :: ReadS [SOName a]

readPrec :: ReadPrec (SOName a)

readListPrec :: ReadPrec [SOName a]

Show (SOName a)

Defined in Foreign.SharedObjectName.Internal

Methods

showsPrec :: Int -> SOName a -> ShowS

show :: SOName a -> String

showList :: [SOName a] -> ShowS

Storable (SOName a)

Defined in Foreign.SharedObjectName.Internal

Methods

sizeOf :: SOName a -> Int

alignment :: SOName a -> Int

peekElemOff :: Ptr (SOName a) -> Int -> IO (SOName a)

pokeElemOff :: Ptr (SOName a) -> Int -> SOName a -> IO ()

peekByteOff :: Ptr b -> Int -> IO (SOName a)

pokeByteOff :: Ptr b -> Int -> SOName a -> IO ()

peek :: Ptr (SOName a) -> IO (SOName a)

poke :: Ptr (SOName a) -> SOName a -> IO ()

hPutSOName :: Handle -> SOName a -> IO ()

Write a shared object name into somwhere referenced by a handle. Useful for sending references to other processes via pipes.

hGetSOName :: Handle -> IO (Maybe (SOName a))

Read a shared object name from somwhere referenced by a handle. Returns Nothing if hGetBuf gets less than 32 bytes. Useful for sending references to other processes via pipes.

unsafeWithSOName :: SOName a -> (CString -> IO b) -> IO b

Use a pointer to a C string to pass to some low-level (e.g. foreign) functions. SOName is asserted immutable, so do not modify it!

genSOName :: IO (SOName a)

Generate a new unique shared object name.

newEmptySOName :: IO (SOName a)

Allocate a new shared object name.
