Hello,
In the native skin for Xenomai 2.6.x, it was possible to create a
0-priority task - a Xenomai task that spends its life in secondary
mode except when calling/interacting with Xenomai services that would
temporarily promote it to primary mode.
Is it possible to create a 0-priority task through the Cobalt skin?
What are the calls/arguments needed?
Thanks in advance!

The equivalent is creating a thread using pthread_create() with the
SCHED_OTHER policy (which requires priority 0 in the sched_param
settings). libcobalt's pthread_setschedparam() can be used for the same
purpose on an existing thread.
