+-- |Resize a memory area that was allocated with 'malloc' or 'mallocBytes'
+-- to the given size. The returned pointer may refer to an entirely
+-- different memory area, but will be sufficiently aligned for any of the
+-- basic foreign types that fits into a memory block of the given size.
+-- The contents of the referenced memory area will be the same as of
+-- the original pointer up to the minimum of the original size and the
+-- given size.
+--
+-- If the pointer argument to 'reallocBytes' is 'nullPtr', 'reallocBytes'
+-- behaves like 'malloc'. If the requested size is 0, 'reallocBytes'
+-- behaves like 'free'.
