Subjectsigcontext on Linux-ppc in user space
Does anyone know how to get at the struct sigcontext in a signal handler
on Linux for powerpc? sigaction of course lets you create a signal
handler as a function with the prototype void(*)(int, siginfo_t *, void
*)
where the last argument, a pointer to void, is the sigcontext. I believe
that the last argument is NOT defined by POSIX and so is implementation
dependent.

On Intel it seems sufficient to use #include <asm/sigcontext.h>
to get the definition of struct sigcontext, and then get the values
you'd like out of the signal handler. But on Linux for powerpc, the same
thing doesn't work. Does anyone know what the trick is here to
accomplish this?

Thanks in advance
