In one program I'm updating, I have one rt-task created with the V1
functions and made periodic with:
rt_task_init()
rt_task_make_periodic()
and in the task I use
rt_task_wait()
in which I want to port to V3 so I can use some of the newer features of
RTLinux. Judging from some examples, it looks like all need to do is to use
is:
pthread_attr_init()
pthread_create()
pthread_make_periodic_np()
pthread_setchedparam()
and in the task I use
pthread_wait_np()
(with appropriate arguments.)
Is this really all I have to do?
It appears to me that the thread created in this way should function exactly
like the task created with the V1 method and apart from changing
rt_task_wait() to pthread_wait_np() I should need no other changes to the
code of the new thread to get exactly the same performance as the original
task. Are the new thread and the old task really completely equivalent?
Are there any other gotchas I should be concerned about in getting to the
point where I have the new thread cycling like the old task did?
