Experimental Physics and Industrial Control System
Hi all,
I have a (EPICS 3.14) CAS application that provides a variable-sized array of
UInt8. Unfortunately, I fail to tell the CA client that the array size has
changed. All clients are stuck with the array size they receive when they
first connect.
On the server side, I have:
casEventMask select(getCAS()->valueEventMask() | getCAS()->logEventMask());
select |= getCAS()->propertyEventMask();
m_value->dump();
postEvent(select, *m_value);
The dump correctly reflects the new size:
----------dump This=0x89d3b8---------
dimension=1 app-type=16 Atomic
prim-type=aitUint8(aitEnumUint8)
20 values=<
0x76 0x45 0x65 0x52 0x78 0x50 0x4c 0x39 0x33 0x31 0x74 0x71 0x37 0x37 0x59 0x34 0x65 0x55 0x71 0x58 >
ref-count=2
total-bytes=336, data-size=256, element-count=256
destructor=NULL
(0) 0x8a0b90 first=0 count=256
LocalDataFormat NetworkDataFormat
-------------------------------------
----------dump This=0x89d400---------
dimension=1 app-type=16 Atomic
prim-type=aitUint8(aitEnumUint8)
20 values=<
0x47 0x49 0x46 0x38 0x39 0x61 0x29 0x00 0x19 0x00 0xf7 0x00 0x00 0x00 0x00 0x00 0x00 0xe7 0x00 0x42 >
ref-count=2
total-bytes=1280, data-size=1199, element-count=1199
destructor=NULL
(0) 0x8a0b98 first=0 count=1199
LocalDataFormat NetworkDataFormat
-------------------------------------
and clients always receive the correct length for their initial values.
From debug outputs I know that PV::maxBound(unsigned) is not called when
the length changes.
Is it possible to post an event to have a client (I tried camonitor and CSS)
update the stored length information?
Thanks,
Michael
