dlsym :: DL -> String -> IO (FunPtr a)
dlerror :: IO String
dlclose :: DL -> IO ()

Documentation

module System.Posix.DynamicLinker.Prim

dlopen :: RawFilePath -> [RTLDFlags] -> IO DL Source

dlsym :: DL -> String -> IO (FunPtr a)Source

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

dlerror :: IO String Source

dlclose :: DL -> IO ()Source

withDL :: RawFilePath -> [RTLDFlags] -> (DL -> IO a) -> IO aSource

withDL_ :: RawFilePath -> [RTLDFlags] -> (DL -> IO a) -> IO ()Source

undl :: DL -> Ptr ()Source

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