waiting on ports

I have a series of ports, c. I want to wait on all of them, but I also want to specify the timeout parameter, 5 seconds. How can I do this? ready: wait [c 5] does not work. Matt

Hi Matt, I am not sure if I understand what you mean by a series of ports. You can specify the timeout for TCP ports using: port: open tcp:192.1.1.1:5001 port/timeout: 5 I hope this is a start.

For instance c/1 is one port, c/2 is a different port, etc. So I want to do a wait on all of them. wait c works fine, but I have to wait for the network timeout if there is no activity on the ports. For a single port you can do a command like wait [c/1 5] so that it listens on c/1 for 5 seconds. So I want to do the same thing, but with all of the ports. So the command would be something like: wait [c 5], but this generates an error. Matt Hi Matt, I am not sure if I understand what you mean by a series of ports.

shouldn't it be: I do not know how c is built but supposing you did: c: [port1 port2 port3] you could: append c 5 ; add timeout value to block OR: add timeout directly: c: [port1 port2 port3 5] wait c ; call wait on the block -max ----------- meteor Studios, T.D. ----------- Never Argue with an idiot.

Hi Matt, On Monday, August 25, 2003, 4:00:02 PM, you wrote: MM> I have a series of ports, c. I want to wait on all of them, but I also want MM> to specify the timeout parameter, 5 seconds.

One way is: wait compose [(c) 5] or: wait append copy c 5 You could also add the timeout to your list of ports, like: append c 5 ; ... wait c Regards, Gabriele. -- Gabriele Santilli <[g--santilli--tiscalinet--it]> -- REBOL Programmer Amiga Group Italia sez.

Use wait/all --Maarten

Hi Matt, Have you tested ... wait append c 5 as wait expects a block of value, not a block of block. Regards Patrick

That works great, but only in the console. Any idea why it wouldn't work in view?

There is a function called do-events which launches an empty wait loop (since view creates an event loop handler, it starts waiting for events, I guess its a port too). do-events: func [ "Process all View events." ][ wait [] ] you can see that in do-events, wait has no timeout... I am not sure how it ties in with message port handling... you might want to open your window with view/only (which does not start event handling) and then start your own wait with ports and timeout selected, like we were all talking about... then any view events will react until the timeout appears and the wait returns... ITHINK .... at which point you could relauch only a wait [] (to continue with view events, or start other ports etc)... or pop up a message or whatever... I'm not sure why you need the timeout... I cannot test it, but maybe this does not work... in any case, I'll have opened a door which you or someone else might want to explore...

Hi Max, MOA> you might want to open your window with view/only MOA> (which does not start event handling) I think you mean VIEW/NEW. -- Gregg

yessssss, sorry !!!! VIEW/NEW -max all that talk about files <-> blocks had my mind mixed up ;-)
