List of weak pointers to childs with concurrent access
closeAllChildren :: Statement stmt => ChildList stmt -> IO ()Source
Close all children. Intended to be called by the disconnect
function
in Connection
.
There may be a potential race condition wherein a call to newSth at the same time as a call to this function may result in the new child not being closed.
addChild :: Statement stmt => ChildList stmt -> stmt -> IO ()Source
Adds a new child to the existing list. Also takes care of registering a finalizer for it, to remove it from the list when possible.
newChildList :: IO (ChildList stmt)Source
new empty child list
