Re: redirecting the standard output

Even if you some hope open the file (try just simple Out_File for the mode)
you may
run into problems.

On older vxWorks at least, writes to a file descriptor tied to the null
device always return
an error status so my compiler was seeing that and raising an exception on
all output.

I ended up having to create a null device driver that always returned good
status for writes.
