Types
type TimeoutAction = IO () Source #
An action to be performed on timeout.
Manager
initialize :: Int -> IO Manager Source #
Creating timeout manager which works every N micro seconds where N is the first argument.
stopManager :: Manager -> IO () Source #
Stopping timeout manager with onTimeout fired.
killManager :: Manager -> IO () Source #
Killing timeout manager immediately without firing onTimeout.
Arguments
| :: Int | timeout in microseconds |
| -> (Manager -> IO a) | |
| -> IO a |
Call the inner function with a timeout manager.
Registration
registerKillThread :: Manager -> TimeoutAction -> IO Handle Source #
Registering a timeout action of killing this thread.
Control
tickle :: Handle -> IO () Source #
Setting the state to active.
Manager turns active to inactive repeatedly.
cancel :: Handle -> IO () Source #
Setting the state to canceled.
Manager eventually removes this without timeout action.
