forceSwapTMVar :: TMVar a -> a -> STM (Maybe a) #
Non-blocking swap of TMVar irreguardless if it previously contained a value or not. Returns what was in the TMVar (if exists)
waitTillEmptyTMVar :: TMVar a -> a -> STM () #
Block until TMVar is empty. The argument a is used to try to put into TMVar, but is taken out again in the same transaction
waitTillFullTMVar :: TMVar a -> STM () #
Block until TMVar is full.
