What to do when close() fails?

[Chip Salzenberg]

A question for those of you with UNIX kernel source code:

     If you call open() on a device file, and you then call close() on
     the open file descriptor, but the driver for that device reports an
     error on the close, is the file descriptor closed or not?

We are running SCO Xenix System V, but we're interested in the results
for all types of machines.

Please E-mail and I'll post a summary.
