2. dlerror :: IO String

5. moduleError :: IO String

   unix	System.Posix.DynamicLinker.Module.ByteString

6. getLoginName :: IO String

   unix	System.Posix.User

   getLoginName calls getlogin to obtain the login name associated with the current process.

7. getEffectiveUserName :: IO String

   unix	System.Posix.User

   getEffectiveUserName gets the name associated with the effective UserID of the process.

8. getProgName :: IO String

   base-compat	System.Environment.Compat

   Computation getProgName returns the name of the program as it was invoked. However, this is hard-to-impossible to implement on some non-Unix OSes, so instead, for maximum portability, we just return the leafname of the program as invoked. Even then there are some differences between platforms: on Windows, for example, a program invoked as foo is probably really FOO.EXE, and that is what getProgName will return.

9. getContents' :: IO String

   base-compat	System.IO.Compat

   The getContents' operation returns all user input as a single string, which is fully read before being returned (same as hGetContents' stdin).

10. getLine :: IO String

    hedgehog	Hedgehog.Internal.Prelude

    Read a line from the standard input device (same as hGetLine stdin).
