Hi, I had a problem with an RTDM driver: /proc/xenomai/rtdm/open_fildes could not close its descriptors. So, I tried with trunk which has auto-cleanup of RTDM descriptors, to see if descriptors would be closed, the descriptors were not auto-closed when killing my application either. After a little investigation, it appears that the problem is that my drivers had a real-time close handler but no non-realtime handler, so when close was invoked from a non real-time context (either /proc/xenomai/rtdm/open_fildes, or the auto-cleanup routine), the default close handler installed by RTDM simply returned -38 and close aborted.
The way to fix this issue was rather simple: implement a non real-time close handler, but I find this behaviour a bit disturbing, maybe implementing a non real-time close handler could be mandatory ? -- Gilles Chanteperdrix. _______________________________________________ Xenomai-core mailing list Xenomaiemail@example.com https://mail.gna.org/listinfo/xenomai-core
