hReady -package:ghc-internal

hReady :: Handle -> IO Bool
base System.IO, base-prelude BasePrelude, pathtype System.Path.IO
Computation hReady hdl indicates whether at least one item is available for input from handle hdl. This operation may fail with:
hReady :: MonadIO m => Handle -> m Bool
unliftio UnliftIO.IO
Lifted version of hReady
threadYield :: (HasCallStack, MonadIO m) => m ()
gi-glib GI.GLib.Structs.Thread
Causes the calling thread to voluntarily relinquish the CPU, so that other threads can run. This function is often used as a method to make busy wait less evil.
ThreadYielding :: ThreadStopStatus
ghc-events GHC.RTS.Events
testWithReadyApplication :: AreProcs procs => (Port -> IO ()) -> HList procs -> (HandlesOf procs -> IO Application) -> ((HandlesOf procs, Port) -> IO a) -> IO a
tmp-proc System.TmpProc.Warp
Set up some ProcHandles then run an Application that uses them on a free port. Allows the app to configure itself using the tmp procs, then provides a callback with access to the handles. Also runs a ready action that to determine if the application started correctly. The tmp procs are shut down when the application is shut down.
testWithReadyTLSApplication :: AreProcs procs => TLSSettings -> (Port -> IO ()) -> HList procs -> (HandlesOf procs -> IO Application) -> ((HandlesOf procs, Port) -> IO a) -> IO a
tmp-proc System.TmpProc.Warp
Like testWithReadyApplication; the port is secured with TLSSettings.
