Let me propose a revised scheme for midas standard VME calls (mvmestd.h).
Pierre mentioned some limitations before, and I find now also some fields

Before we try to merge the different access scheme for the different VME hardware,
we present the "optimal" configuration for the VMIC setup. This is a first shot so take it
with caution.

Thanks for your contribution. Let me try to map your functionality to mvmestd calls:

I see that MIDAS installs several set-uid-root programs into /usr/local/bin.
In this age and time of evil computer hackers, this is not a good idea and
we should Do Something (TM) about it. Here is my risk assessment:

I have seen the same behaviour and it annoys me, too. What I did in the past
is a "cleanup" in ODBEdit which removes these open records. I have soem code
in cm_watchdog(), which should take care of that. If a client is dead, it

would be nice to be able to disable them in release code. Under Windows, the

29 Jul 2003, Konstantin Olchanski, , Have to link with -lpthread?

It appears that all midas applications are now required to link with the
pthreads library even if they do not use threads. This is caused by a
pthread_create() call from ss_thread_create() in system.c.
|
|
30 Jul 2003, David Morris, , Have to link with -lpthread?
|
The change is required to support implementation of pthreads in the Linux
compile of Midas. This was added recently. I believe pthreads is also needed
for ROOT based compiles.
