I'll try this out later today, Dave.

I'm preparing a POSIX shared memory driver (PSHM) for ntp to address a
few issues that exist with the present SHM driver. In no particular
order, these are:
o POSIX (not SVID) shared memory
-- POSIX shared memory namespace rather than hexadecimal constant
-- avoids 0x4e545030 [...] Big un

Sounds good, Bruce. The best way to get that integrated with ntpd is
first integrate it with the existing refclock_s
Bruce,
I take it your driver will replace or modify an existing driver, right?
Adding a new driver to the current population of over 40 drivers is not
a practical course.

Yes, it looks good, and thanks for clarifying the "before" was using
the user-mode PPS hack in the Windows port of ntpd.
However, it doesn't seem to be working anything like as well as
nominally
the same software installed in 32-bit Windows on PC Stamsund. Compare

Folks,
I have received the following announcement:

The MoD has informed Ofcom of the following GPS jamming exercise:
Dates: Jamming will be conducted on a maximum of 3 week-days in the period
10-21 July 2011.Times: 0900 -1730 BST.
Location:
Bruce,
Please see http://support.ntp.org/bin/view/Dev/RefclockShmV2 and
communicate with folks who have been thinking about this (me, Miroslav,
Dave Hart, just to name the first 3 folks who come to mind).
Making notes on either the above wiki topic or on a separate sub-topic
might be even better,
Bruce,
If you want to do this yourself that will be wonderful.
If you think this might make a good GSoC project, we should know
tomorrow if we have been accepted into GSoC 2011 and that would be an
option, too.

Long term, possibly; but migrating code that uses an existing driver
isn't likely to happen overnight.
I see no problem though in reusing an abandoned driver numbe

Actually nailing down the sizes of objects is a really good idea when
