You should check errno.  If it's EINTR, loop back immediately.  If it's EWOULDBLOCK and you're doing the accept in a non-blocking fashion, you can just ignore the error and wait for the next async connection indication.  Otherwise it's a real error and you should report it accordingly.

Share and Enjoy
