Hi I am interested in using this also for taking snapshots. Did you consider using a single option, or allowing either a file descriptor or a pathname, or including also the event default of "disabled". e.g. add "--control" and support all of: --control --control 11 --control 11,15 --control 11,15,disabled --control 11,,disabled --control /tmp/my-perf.fifo --control /tmp/my-perf.fifo,/tmp/my-perf-ack.fifo --control /tmp/my-perf.fifo,/tmp/my-perf-ack.fifo,disabled --control /tmp/my-perf.fifo,,disabled Regards Adrian
