Re: [pok-devel] POK / ARINC653 - DEADLINE_TYPE

[Matias Hastaran <matias.hastaran@xxxxxxxxxxx>]

thanks for your last answer.

I take the opportunity to ask you 2 other questions.
First how can I check if the preemption is enabled or disabled?
Secondly, less important, how can I check if a thread is periodic or aperiodic?
That information will be used to process some check for arinc. If I cannot have these information I just won't do these tests for the moment.

Thanks a lot
Matias
