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 thr= eads, so I think that at creation they inherits all signal masks and handle= rs 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 t= here are some signals (eg SIGWINCH) needed by Xenomai for inter-task commun= ication?

By the way, is there a method in Xenomai to initialize all = RT_TASK structure fields without use field names (eg PTHREAD_MUTE= X_INITIALIZER)?
I use this simple define:

#define RT_TASK_RE= SET(task) task.opaque=3D0 , task.opaque2=3D0

but it works only for k= ernel tasks (in include/native/task.h RT_TASK structure isn't the same for = kernel/non kernel tasks).
I think that a struct initializer into library= could be a next feature.

Thank you,regards.
