[Discuss-gnuradio] Ring-buffer allocation

2009-02-01 Thread Marcus D. Leech
Eric, et al: How does the ring-buffer allocation work in Gnu Radio? For example, if I'm shuffling vectors around--let's say 1600 complex items per vector, how many of these vector-sized "items" are allocated in a ring buffer between a producer and a consumer? How much room is there for sca
