The double-mapped ring buffer trick is so clever I can't help but wish I invented it. :) Here's the code for the GNU radio implementation described in the article, it's a good reference for some various ways to set up the mappings: https://github.com/gnuradio/gnuradio/blob/master/gnuradio-runtime/lib/vmcircbuf_createfilemapping.cc https://github.com/gnuradio/gnuradio/blob/master/gnuradio-ru... https://github.com/gnuradio/gnuradio/blob/master/gnuradio-runtime/lib/vmcircbuf_mmap_shm_open.cc https://github.com/gnuradio/gnuradio/blob/master/gnuradio-ru... https://github.com/gnuradio/gnuradio/blob/master/gnuradio-runtime/lib/vmcircbuf_mmap_tmpfile.cc https://github.com/gnuradio/gnuradio/blob/master/gnuradio-ru...
