Dynamic linker support through dlopen()

module System.Posix.DynamicLinker.Prim

dlopen :: FilePath -> [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 :: String -> [RTLDFlags] -> (DL -> IO a) -> IO a Source

withDL_ :: String -> [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
