| |
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?
