Dear all,
I'm having trouble on SPARC/Linux (of both the 32 and 64 varieties)
getting at the third argument of POSIX sa_sigaction signal handlers.
Consider the following code (a simplified version of what I'm actually
trying to do):
--- Cut here ---
#include <stdlib.h>
#include <sys/ucontext.h>
#include <signal.h>
void sigsegv_handler (int signo, siginfo_t *info, void *data) {
return;
}
int main () {
int *foo;
struct sigaction sa;
sa.sa_sigaction = sigsegv_handler;
sa.sa_flags = SA_SIGINFO | SA_RESTART;
sigaction(SIGSEGV, &sa, NULL);
foo = NULL;
*foo = 3;
return 0;
}
--- Cut here ---
Running under gdb reveals that, whereas on alpha, x86 and ppc the
third argument to sigsegv_handler is a pointer to a ucontext
structure, on sparc and sparc64 I get NULL.
Am I doing something wrong, or is the ucontext argument simply not yet
implemented on the sparc architecture?
Many thanks,
Christophe
