Select blocks on readfds if a read from the file would block; that is never the case with a file: you will either get data, or you will get an EOF. Select blocks on writefds if a write to the file would block; that is never the case with a file: you will either successfully write, or you will get an error, e.g. as a result of exceeding quota, etc.. Therefore a select for reads or writes on a disk file should always return true. -- Terry _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
