waitAny :: [Async a] -> IO (Async a, a)async Control.Concurrent.Async Wait for any of the supplied Asyncs to complete. If the first to complete throws an exception, then that exception is re-thrown by waitAny. The input list must be non-empty. If multiple Asyncs complete or have completed, then the value returned corresponds to the first completed Async in the list.
waitAnyCancel :: [Async a] -> IO (Async a, a)async Control.Concurrent.Async Like waitAny, but also cancels the other asynchronous operations as soon as one has completed.
waitAnyCatch :: [Async a] -> IO (Async a, Either SomeException a)async Control.Concurrent.Async Wait for any of the supplied asynchronous operations to complete. The value returned is a pair of the Async that completed, and the result that would be returned by wait on that Async. The input list must be non-empty. If multiple Asyncs complete or have completed, then the value returned corresponds to the first completed Async in the list.
waitAnyCatchCancel :: [Async a] -> IO (Async a, Either SomeException a)async Control.Concurrent.Async Like waitAnyCatch, but also cancels the other asynchronous operations as soon as one has completed.
waitAnyCatchSTM :: [Async a] -> STM (Async a, Either SomeException a)async Control.Concurrent.Async A version of waitAnyCatch that can be used inside an STM transaction.
waitAnySTM :: [Async a] -> STM (Async a, a)async Control.Concurrent.Async A version of waitAny that can be used inside an STM transaction.
cancelMany :: [Async a] -> IO ()async Control.Concurrent.Async.Internal Cancel multiple asynchronous actions by throwing the AsyncCancelled exception to each of them in turn, then waiting for all the Async threads to complete.
waitAny :: [Async a] -> IO (Async a, a)async Control.Concurrent.Async.Internal Wait for any of the supplied Asyncs to complete. If the first to complete throws an exception, then that exception is re-thrown by waitAny. The input list must be non-empty. If multiple Asyncs complete or have completed, then the value returned corresponds to the first completed Async in the list.

The value returned is a pair of the Async that completed, and the result that would be returned by wait on that Async. The input list must be non-empty. If multiple Asyncs complete or have completed, then the value returned corresponds to the first completed Async in the list.
