The flow-graph writes to 3 FIFOs. I fire off 3 reader threads that read the FIFOs, and only dump data when the other part of the program determines that it's in a "triggered" situation, since I'm both reading and writing, I refer to that as "reflexive".On Fri, 20 Apr 2012, Marcus D.

It maintains the existing semantic for the gr_file_sink, and since I already have some "helper" Python code to deal with trigger detection,
it was a natural place to put it. Works just fine. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
