select()

[Todd M. Grimm]

I am using select() to test whether there are bytes on a socket to read 
without blocking my program to check on this.

The problem is that even when there is no data it returns a 1 to say that 
there is data. This causes my program to try a read which blocks because 
there really is no data.

I saw several messages in the archives of this list about this, but all I 
could find were questions. No one ever seemed to answer the question.

Please let me know if you know how to get select() to work right or if 
there is a nother way to test for bytes without blocking.

Thanks,
Todd grimm
