waitForEvents :: [Event] -> IO ()
Waits on the host thread for commands identified by event objects in event_list to complete. A command is considered complete if its execution status is CL_COMPLETE or a negative value.
eventCommandQueue :: Event -> IO CommandQueue
The CommandQueue associated with an Event
eventCommandType :: Event -> IO CommandType
The CommandType of an Event
setEventCompleteCallback :: Storable a => Event -> a -> (CommandExecStatus -> a -> IO ()) -> IO ()
The OpenCL standard version 1.1 (page 146) mentions CL_COMPLETE as the only command execution callback types where a callback can be registered. This is the callback set by this function.
setUserEventStatus :: Event -> Int -> IO ()
