Synopsis

- initObjLinker :: IO ()
- loadDLL :: String -> IO (Maybe String)
- loadArchive :: String -> IO ()

initObjLinker :: IO ()

loadDLL :: String -> IO (Maybe String)

loadDLL loads a dynamic library using the OS's native linker (i.e. dlopen() on Unix, LoadLibrary() on Windows). It takes either an absolute pathname to the file, or a relative filename (e.g. "libfoo.so" or "foo.dll"). In the latter case, loadDLL searches the standard locations for the appropriate library.

loadArchive :: String -> IO ()

loadObj :: String -> IO ()

unloadObj :: String -> IO ()

insertSymbol :: String -> String -> Ptr a -> IO ()

lookupSymbol :: String -> IO (Maybe (Ptr a))

resolveObjs :: IO SuccessFlag
