module Data.IORef
modifyIORef' :: IORef a -> (a -> a) -> IO () #
Strict version of modifyIORef
Since: base-4.6.0.0
atomicModifyIORef' :: IORef a -> (a -> (a, b)) -> IO b #
Strict version of atomicModifyIORef
. This forces both the value stored
in the IORef
as well as the value returned.
Since: base-4.6.0.0
atomicWriteIORef :: IORef a -> a -> IO () #
Variant of writeIORef
with the "barrier to reordering" property that
atomicModifyIORef
has.
Since: base-4.6.0.0
