Synopsis

module System.Posix.DynamicLinker.Prim

valuedlopen :: FilePath -> [RTLDFlags] -> IO DL

valuedlsym :: DL -> String -> IO (FunPtr a)

dlsym returns the address binding of the symbol described in symbol, as it occurs in the shared object identified by source.

valuedlerror :: IO String

valuedlclose :: DL -> IO ()

valuewithDL :: FilePath -> [RTLDFlags] -> (DL -> IO a) -> IO a

valuewithDL_ :: FilePath -> [RTLDFlags] -> (DL -> IO a) -> IO ()

valueundl :: DL -> Ptr ()

undl obtains the raw handle. You mustn't do something like withDL mod flags $ liftM undl >>= p -> use p
