Subject: Waveform Record Device Support

Hi All,

I am integrating a turn-by-turn BPM system into EPICS and would like to
store the raw BPM pickup data in a waveform record.  Due to the nature
of the system, each run can result in a different number of samples for
each BPM pickup, so the array size is unknown in advance and could
potentially be different every run.

Is it possible to resize the number of waveform record elements in my
device support, or do I have to size the waveform record in advance for
the maximum number of samples that could be expected.  Most of the
examples of waveform device support I see read the nelm field and return
this fixed amount of data via the records bptr.

Thanks,

Graham
