Exact lookup

1. getLine :: IO String

   base	Prelude

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

2. getContents :: IO String

   base	Prelude

   The getContents operation returns all user input as a single string, which is read lazily as it is needed (same as hGetContents stdin).

3. getProgName :: IO String

   base	System.Environment

   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.

4. getProgName :: IO String

   base	System.Environment.Blank

   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.

5. getLine :: IO String

   base	System.IO

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

6. getContents :: IO String

   base	System.IO

   The getContents operation returns all user input as a single string, which is read lazily as it is needed (same as hGetContents stdin).

7. getContents' :: IO String

   base	System.IO

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

8. getLine :: IO String

   amazonka-core	Amazonka.Prelude

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

9. getContents :: IO String

   amazonka-core	Amazonka.Prelude

   The getContents operation returns all user input as a single string, which is read lazily as it is needed (same as hGetContents stdin).

10. dlerror :: IO String

    unix	System.Posix
