Subject: [Xenomai-core] rt_pipe_create() and P_MINOR_AUTO
Date: Thu, 12 Jan 2006 18:02:33 -0500	[thread overview]
Message-ID: <20060112180233.T15311@domain.hid> (raw)

Hello,

First things first: I am using version Xenomai 2.0.1 on a recompiled
Ubuntu kernel version 2.6.14.3.

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.  <mope>  

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.
