I presume that it is safe for task 'X' to suspend task 'Y' when 'Y' is
asleep, or waiting on a message Q.
And possibly when waiting on a semaphore.
So, is it possible to obtain the state of the task to be suspended, and if
it's in one of those states then I can suspend it.
I see that the task state is listed in the monitor 'task' command, but this
code is in RTEMS, and I can't see an obvious rtems_task_xxx API call to
obtain this info. Is there one?

Nick
