Rather than just ignoring the offset, you should check for -1 and return ESPIPE otherwise, so pread/pwrite fail as they should.
I'd say you should use getdport at the beginning and use io_read and the like directly instead of read. That is more efficient and also shows what the client calls look like. But if you are deliberately using the POSIX calls to make the example more clear, then you should change io_readable to ioctl(,FIONREAD) and have it be complete. You're using fork2 just to avoid zombies, right? I would say that you should instead do a simple reaping loop with WNOHANG at convenient times like when you read EOF on a pipe. That also gives you the opportunity to print an error if you have a stderr and the spawned program exits abnormally. I don't like the name /hurd/run so much. Maybe /hurd/pipeto? _______________________________________________ Bug-hurd mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-hurd
