Synopsis
- getPtr :: ForeignPtr a -> Ptr a
- setPtr :: ForeignPtr a -> Ptr a -> ForeignPtr a
- updPtr :: (Ptr a -> Ptr a) -> ForeignPtr a -> ForeignPtr a
- unsafeWithForeignPtr :: ForeignPtr a -> (Ptr a -> IO b) -> IO b

getPtr :: ForeignPtr a -> Ptr a Source #
setPtr :: ForeignPtr a -> Ptr a -> ForeignPtr a Source #
updPtr :: (Ptr a -> Ptr a) -> ForeignPtr a -> ForeignPtr a Source #
unsafeWithForeignPtr :: ForeignPtr a -> (Ptr a -> IO b) -> IO b Source #
A compatibility wrapper for unsafeWithForeignPtr
provided
by GHC 9.0.1 and later.
Only to be used when the continuation is known not to unconditionally diverge lest unsoundness can result.
