Hi to all,
I would build an application where only one of real-time tasks executes a custom signal handler to respond to a set of signals (ex SIGINT, SIGTERM).
Xenomai tasks are also POSIX threads, so I think that at creation they inherits all signal masks and handlers from parent thread.
So, what I can do in my app is reset signal mask to block all signals when new task starts.
Can I block all signals or there are some signals (eg SIGWINCH) needed by Xenomai for inter-task communication?
By the way, is there a method in Xenomai to initialize all RT_TASK structure fields without use field names (eg PTHREAD_MUTEX_INITIALIZER )?
I use this simple define:
