Hi,
If this has been asked before, sorry I missed it. But with QNX4.25 patch
D there’s a new util called “vdir”. Gathering from the update notes and
the usage message, it would appear to be some sort of a virtual
directory in RAM, right? But if that’s the case, what’s the difference
with a ram disk? (I.e. a mounted /dev/ram)
regards,
rick
The two big differences I see are:

Note that it was design for small foot print. It does no handle huge files
or number of files very well.
With the beta I tried with over 64 megs of stuff in it, it became slower
then
a HD. But with little data to manage it flies.

The two big differences I see are:
- vdir can be started and stopped without restarting Fsys
- vdir can dynamically resize itself (alloc/dealloc RAM)
Unfortunately, the options are a little cryptic, and the documentation is
sparse.
