Hi,
getProgName is only useful in case you want to print the program name to the screen. You cannot actually use it to do anything interesting programmatically (like execv:ing the program.) I suggest we add getFullProgName which does the sensible thing of returning argv[0]. Here's an implementation:
getFullProgName :: IO String getFullProgName = alloca $ \ p_argc -> alloca $ \ p_argv -> do getFullProgArgv p_argc p_argv peek p_argv >>= peek >>= peekCString
foreign import ccall unsafe "getFullProgArgv" getFullProgArgv :: Ptr CInt -> Ptr (Ptr CString) -> IO ()
