Re: streamdevice exceptions

[Jeong Han Lee <citadel.lee@gmail.com>]

Hi Pedro,

  The following site may give a hint to you

http://epics.web.psi.ch/software/streamdevice/doc/tipsandtricks.html#readmany


  And the following codes may help to figure out what you want to do. I 
hope I understand what you want correctly.

  Thanks,
  Han
