The existence of the undocumented function rt_pipe_bind() makes me think so. http://www.rts.uni-hannover.de/xenomai/lxr/source/include/native/pipe.h?v=SVN-2.4.x#163 Wolfgang. ^ permalink raw reply [flat|nested] 2+ messages in thread

A message pipe always connects a real-time endpoint with a regular chardev endpoint. We could enable this feature in 2.5, but now, we have buffer objects available as well in the trunk/, which would make this redundant. > http://www.rts.uni-hannover.de/xenomai/lxr/source/include/native/pipe.h?v=SVN-2.4.x#163 > > Wolfgang. > > _______________________________________________ > Xenomai-help mailing list > Xenomai-help@domain.hid > https://mail.gna.org/listinfo/xenomai-help > -- Philippe. ^ permalink raw reply [flat|nested] 2+ messages in thread
