Please try this story: mkfifo /tmp/pipe.flog sleep 1000000 > /tmp/pipe.flog & while true ; do cat bytes > /tmp/pipe.flog ; done & fgfs --generic=file,in,$rate,/tmp/pipe.flog,$protocol Now that readline does not do seeks, it can read named pipes (FIFOs) just fine, and this opens up all sorts of non-hackish way of solving the SIGGRAPH problem ... and a host of previously-unsolved problems as well. For example, it allows you to switch from one stream of bytes to another without restarting fgfs. Seems like a win/win to me. If this story is not good enough, please clarify the question. ============ Hint: The sleep statement ensures that the reader (fgfs) will not see an EoF at the point where one cat of bytes ends and the next begins. ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
