Hi Heinz,


I have recently tested some of the examples in https://github.com/epics-base/exampleCPP and they are working with EPICS 7.0.2.


Cheers,

Will

Subject: I'm looking for a pvacces example to read PVStructure

I'm looking for a pva example c++ program which I can currently use (with Epics 7).

Unfortunately the examples I've found on the net don't work at all.

Above all, there seems to be a little confusion between PVAClient and pvac? (Or I don't get it)

I have a client that wants to read the PVStructure of a PV and then put new data  into
NTTable vector fields (x, y, z and time_index):

humma-kavula:~ junkes$ pvlist 0xB9EC6A5C00000000C2AFA421
CRYVISIL:STM:FASTSCAN:IMAGE_CHUNK

humma-kavula:~ junkes$ pvinfo CRYVISIL:STM:FASTSCAN:IMAGE_CHUNK
CHANNEL  : CRYVISIL:STM:FASTSCAN:IMAGE_CHUNK
STATE    : CONNECTED
ADDRESS  : 141.14.133.59:53379
epics:nt/NTTable:1.0
    string[] labels
    structure value
        double[] x
        double[] y
        double[] z
        int[] time_index
    string descriptor
    alarm_t alarm
        int severity
        int status
        string message
    time_t timeStamp
        long secondsPastEpoch
        int nanoseconds
        int userTag
    int counter
