I am using sigaction in a RT thread.
I have read the man pages for sigaction (and sigprocmask). It says that the funktins have not
been 100% completed yet, and that what i think is the problem. I have also read looked at the
"speaker example" and this gives some idea what to be done.

BTW.
I have send another mail about a "bug" in communikation between RT-linux and linux.
->Ignore it
I have read "A linux-based Real-Time Operating System" by Michael Barabanov, and this doc
gives the reason way this can not be done.
( maybe my code could be used as en example of what goes wrong)
