Add forkOSUnmasked (patch)
This patch simply adds forkOSUnmasked
to Control.Concurrent:
-- | Like 'forkIOWithUnmask', but the child thread is a bound thread,
-- as with 'forkOS'.
forkOSWithUnmask :: ((forall a . IO a -> IO a) -> IO ()) -> IO ThreadId
forkOSWithUnmask io = forkOS (io unsafeUnmask)
I ran sh validate
, and no new failures were introduced. I'll push it to master in a few days, unless someone objects.
For GHC < 7.8, forkOSWithUnmask
can be achieved using forkOS
and block, but block
is removed in GHC 7.8. unsafeUnmask
can still be imported from GHC.IO
, however.
