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

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)) Source #

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 Source #

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) Source #

Generate a new unique shared object name.

newEmptySOName :: IO (SOName a) Source #

Allocate a new shared object name.
