Justin,
I revised my earlier test program a little. You might
want to consider placing it in the man page.
Cheers,
Michael

myfunc3(void)
{
int nptrs, j;
#define SIZE 100
void *ptr[SIZE];
char **strings;
nptrs = backtrace(ptr, SIZE);
strings = backtrace_symbols(ptr, nptrs);
if (strings == NULL) {
perror("backtrace_symbols");
exit(EXIT_FAILURE);
}
for (j = 0; j < nptrs; j++)
printf("%s\n", strings[j]);
}
static void /* 'static' means don't export the symbol... */
myfunc2(void)
{
myfunc3();
}
void
myfunc(int ncalls)
{
if (ncalls > 1)
myfunc(ncalls - 1);
else
myfunc2();
}
int
main(int argc, char *argv[])
{
myfunc(3);
exit(EXIT_SUCCESS);
}
