Re: fdescfs functional in 6.1?
I guess I just expected it to print all character device entries for the file descriptors open by my process. Kind of like the old /dev/fd/1 /dev/fd/2 directories used to be under MAKEDEV...

I guess I just expected it to print all character device entries for the file descriptors open by my process. fdescfs prints all file desriptors open by your process, and displays the correct info for each of them. Kind of like the old /dev/fd/1 /dev/fd/2 directories used to be under MAKEDEV... Before devfs, /dev/fd was populated with dummy entries from 0 to 63 and running ls on the directory had no correspondence with what your process actually had open. -- Dan Nelson [EMAIL PROTECTED] ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

It did-- well it printed all the file descriptors open by your process, which in this case was ls. 0, 1, and 2 are stdin, stdout, and stderr (respectfully) and they point to the device you logged into. Try doing ls -la /dev/fd | less and I'll bet 1 will be a pipe? This seems like the correct operation; I'm not sure I understand what you expected and why that's different than what you've observed. Kind of like the old /dev/fd/1 /dev/fd/2 directories used to be under MAKEDEV... How is that the same? MAKEDEV was in the day before devfs, so the device entries needed to be created by the underlying filesystem. In devfs, things are only present if they represent an active device. -- Rick C.
