Re: How to write multi value in a caput message?

["Pearson, Matthew R." <pearsonmr@ornl.gov>]

Hi,

There’s documentation on how to do this on the streamDevice tips & tricks page:
http://epics.web.psi.ch/software/streamdevice/doc/tipsandtricks.html

There’s at least 3 ways to do what you need: waveform/aao, calcout or passing PV names into the protocol function.

Cheers,
Matt
