I guess that is my point though. Not being all too familiar with the inner workings of Linux or glibc, how am I supposed to know which services are not emitting a syscall? I accept that I will lose determinism in calling these services, but I find it odd that it may allow the system to deadlock. If nothing else the syscall-less services should be listed and noted as unsafe. I am new to most of this, but I have went through most of the documentation and, unless I have overlooked it, found nothing mentioning this. _______________________________________________ Xenomai-help mailing list Xenomai-help@gna.org https://mail.gna.org/listinfo/xenomai-help
