stack_violation
stack_violation(3C) Standard C Library Functions stack_violation(3C)NAME
stack_violation - determine stack boundary violation event
SYNOPSIS
#include <ucontext.h>
int stack_violation(int sig, const siginfo_t *sip,
const ucontext_t *ucp);
DESCRIPTION
The stack_violation() function returns a boolean value indicating whether the signal, sig, and accompanying signal information, sip, and
saved context, ucp, represent a stack boundary violation event or a stack overflow.
RETURN VALUES
The stack_violation() function returns 0 if the signal does not represent a stack boundary violation event and 1 if the signal does repre-
sent a stack boundary violation event.
ERRORS
No errors are defined.
EXAMPLES
Example 1 Set up a signal handler to run on an alternate stack.
The following example sets up a signal handler for SIGSEGV to run on an alternate signal stack. For each signal it handles, the handler
emits a message to indicate if the signal was produced due to a stack boundary violation.
#include <stdlib.h>
#include <unistd.h>
#include <ucontext.h>
#include <signal.h>
static void
handler(int sig, siginfo_t *sip, void *p)
{
ucontext_t *ucp = p;
const char *str;
if (stack_violation(sig, sip, ucp))
str = "stack violation.
";
else
str = "no stack violation.
";
(void) write(STDERR_FILENO, str, strlen(str));
exit(1);
}
int
main(int argc, char **argv)
{
struct sigaction sa;
stack_t altstack;
altstack.ss_size = SIGSTKSZ;
altstack.ss_sp = malloc(SIGSTKSZ);
altstack.ss_flags = 0;
(void) sigaltstack(&altstack, NULL);
sa.sa_sigaction = handler;
(void) sigfillset(&sa.sa_mask);
sa.sa_flags = SA_ONSTACK | SA_SIGINFO;
(void) sigaction(SIGSEGV, &sa, NULL);
/*
* The application is now set up to use stack_violation(3C).
*/
return(0);
}
USAGE
An application typically uses stack_violation() in a signal handler that has been installed for SIGSEGV using sigaction(2) with the SA_SIG-
INFO flag set and is configured to run on an alternate signal stack.
