race condition in close socket??
 

Here's my problem.. Seems to only occur on localhost connections because they happen so fast.

(These are nonblocking sockets by the way)

1. I close a socket after its data transfer
2. Accept another incoming conneciton, it seems to get the same fd as the last socket closed.
3. Set the fd_set
4. Enter select loop which falls through
5. Sometimes though after trying to read or write to this new socket I get a Resouce Not Available.

I took out step 1 and everything seems to work fine.

Any possible idea of whats going on? I have an idea that file descriptor information is not immediately cleaned up. If so how can I prevent this?

did you do a "shutdown()" on the socket before closing it ?

yes I do actually. as I stated I believe it to be some sort of race condition because remote connections never produce the race condition it seems. I can also put in a small sleep after the close and everything seems to work. This shouldn't happen though I think.

So you use close(), shutdown() (which direction?) or both?
