I am confused by rt_pipe_create(), specifically, the "minor" parameter. The writeup at http://snail.fsffrance.org/www.xenomai.org/documentation/branches/v2.0.x/html/api/group__pipe.html#ga20 says that: Passing P_MINOR_AUTO causes the minor number to be auto-allocated. In such a case, the name parameter must be valid so that user-space processes may subsequently follow the symbolic link that will be automatically created from /proc/xenomai/registry/pipes/name to the allocated pipe device entry (i.e. /dev/rtp*). Sounds great, but it doesn't seem true. So I have to manage minor usage be hand until P_MINOR_AUTO is implemented, or did I miss something? Thanks, -kb, the Kent who hasn't had a chance to try the 2.6.15 kernel he started playing with last week.
