1. throwErrnoIfMinus1RetryMayBlock :: (Eq a, Num a) => String -> IO a -> IO b -> IO a

   base	Foreign.C.Error

   as throwErrnoIfMinus1Retry, but checks for operations that would block.

2. throwErrnoIfMinus1RetryMayBlock_ :: (Eq a, Num a) => String -> IO a -> IO b -> IO ()

   base	Foreign.C.Error

   as throwErrnoIfMinus1RetryMayBlock, but discards the result.

3. throwErrnoIfMinus1Retry_ :: (Eq a, Num a) => String -> IO a -> IO ()

   base	Foreign.C.Error

   as throwErrnoIfMinus1, but discards the result.

4. throwErrnoIfMinus1_ :: (Eq a, Num a) => String -> IO a -> IO ()

   base	Foreign.C.Error

   as throwErrnoIfMinus1, but discards the result.

5. throwErrnoPathIfMinus1 :: (Eq a, Num a) => String -> FilePath -> IO a -> IO a

   base	Foreign.C.Error

   as throwErrnoIfMinus1, but exceptions include the given path when appropriate.

6. throwErrnoPathIfMinus1_ :: (Eq a, Num a) => String -> FilePath -> IO a -> IO ()

   base	Foreign.C.Error

   as throwErrnoIfMinus1_, but exceptions include the given path when appropriate.

7. createDirectoryIfMissing :: Bool -> FilePath -> IO ()

   directory	System.Directory

   createDirectoryIfMissing parents dir creates a new directory dir if it doesn't exist. If the first argument is True the function will also create all parent directories if they are missing.

8. createDirectoryIfMissing :: Bool -> OsPath -> IO ()

   directory	System.Directory.OsPath

   createDirectoryIfMissing parents dir creates a new directory dir if it doesn't exist. If the first argument is True the function will also create all parent directories if they are missing.

9. hIfModifiedSince :: HeaderName

   http-types	Network.HTTP.Types

   If-Modified-Since

10. hIfMatch :: HeaderName

    http-types	Network.HTTP.Types.Header

    If-Match
