 Kernel::select

pigeon% ri Kernel::select
--------------------------------------------------------- Kernel::select
     select( readArray [, writeArray [errorArray [timeout]]] ) ->
     anArray or nil
------------------------------------------------------------------------
     Performs a low-level select call, which waits for data to become
     available from input/output devices. The first three parameters are
     arrays of IO objects or nil. The last is a timeout in seconds,
     which should be an Integer or a Float. The call waits for data to
     become available for any of the IO objects in readArray, for
     buffers to have cleared sufficiently to enable writing to any of
     the devices in writeArray, or for an error to occur on the devices
     in errorArray. If one or more of these conditions are met, the call
     returns a three-element array containing arrays of the IO objects
     that were ready. Otherwise, if there is no change in status for
     timeout seconds, the call returns nil. If all parameters are nil,
     the current thread sleeps forever.
        select( [$stdin], nil, nil, 1.5 )   #=> [[#<IO:0x4019202c>], [], []]
