1. performGC :: IO ()

   ghc-internal	GHC.Internal.System.Mem

   Triggers an immediate major garbage collection.

2. performMajorGC :: IO ()

   ghc-internal	GHC.Internal.System.Mem

   Triggers an immediate major garbage collection.

3. performMinorGC :: IO ()

   ghc-internal	GHC.Internal.System.Mem

   Triggers an immediate minor garbage collection.

4. c_fork :: IO CPid

   ghc-internal	GHC.Internal.System.Posix.Internals

   No documentation available.

5. checkForInteriorNuls :: FilePath -> CStringLen -> IO ()

   ghc-internal	GHC.Internal.System.Posix.Internals

   Check an encoded FilePath for internal NUL octets as these are disallowed in POSIX filepaths. See #13660.

6. type C_FontsetForeachFunc = Ptr Fontset -> Ptr Font -> Ptr () -> IO CInt

   gi-pango	GI.Pango.Callbacks

   Type for the callback on the (unwrapped) C side.

7. type FontsetForeachFunc = Fontset -> Font -> IO Bool

   gi-pango	GI.Pango.Callbacks

   Callback used when enumerating fonts in a fontset. See fontsetForeach. Since: 1.4

8. type FontsetForeachFunc_WithClosures = Fontset -> Font -> Ptr () -> IO Bool

   gi-pango	GI.Pango.Callbacks

   Callback used when enumerating fonts in a fontset. See fontsetForeach. Since: 1.4

9. drop_closures_FontsetForeachFunc :: FontsetForeachFunc -> FontsetForeachFunc_WithClosures

   gi-pango	GI.Pango.Callbacks

   A simple wrapper that ignores the closure arguments.

10. dynamic_FontsetForeachFunc :: (HasCallStack, MonadIO m, IsFontset a, IsFont b) => FunPtr C_FontsetForeachFunc -> a -> b -> Ptr () -> m Bool

    gi-pango	GI.Pango.Callbacks

    Given a pointer to a foreign C function, wrap it into a function callable from Haskell.
