I'm interested to try spread for Askemos' broadcasting neeeds
(www.askemos.org). From the documentation I see, that SP_receive will
block if there's no message waiting. I have a hard time to cope with
that. Is there any API, which can check, whethere a following
SP_receive would block (simillar to select(2) or poll(2)).
I've seen, that there's a way to delegate filedescriptor watching to
spread, which could basically do what I want. However this would
interfere with other parts of my code, hence it's even more work for
me than spawning a separate thread just to prevent the blocking
behavior. But that would already be quite a weird solution to my
If there's no such API, would it be hard to provide it?
thanks for your help
