Hi,
I just discovered my old programs that use the PCAS library (3.13) no
longer work with the latest release (3.14.10), and I haven't a clue
why. Is there a document somewhere explaining what has changed?
Below are debug output and errors I get when I run the server and
execute "caget halld_event_count" in another window. The server creates
and serves out a PV named halld_event_count.
Output from server:
(caget run in another window at this point, see below for caget
output)
pvExistTest for halld_event_count
createPV for halld_event_count
myPV::createChannel for halld_event_count
myPV::read for halld_event_count
...myPV getVAL for halld_event_count
----------dump This=0x81497b8---------

server tool changed bounds on request - get notify with

...myPV interestDelete for halld_event_count

caget errors:
