[Xenomai-help] rtsocketcan in kernel space

Is it possible to write an application using rtsocketcan to run on kernel
space? I mean, buid a kernel module using functions from rtsocketcan API.

Does anyone have an example?

Thanks in advance

RTDM provides an inter-driver API, see:
http://www.xenomai.org/documentation/branches/v2.4.x/html/api/group__interdrv.html

This is for calling RTDM driver functions from kernel space. But ask yourself 
whether it is really necessary for you to write an application in kernel 
space. User space applications are highly recommended.

Thanks Sebastian. Btw, I'd like to know whether  it's possible to change the
task's period or task's priority on-line. I mean, is there a way to change
the period or priority using rt_task_set_priority or rt_task_set_periodic
calls?

Thanks a lot,

Breno

All this is described in the API documentation, see:
http://www.xenomai.org/documentation/branches/v2.4.x/html/api/group__task.html

In short: Yes, it is possible.
