Check out linux/stacktrace.h
Here is an API reference:
http://www.cs.cmu.edu/afs/cs/Web/People/tekkotsu/dox/StackTrace_8h.html
Should work on all Linux kernels
Here is an alternative example in C from
http://www.linuxjournal.com/article/6391
#include <stdio.h>
#include <signal.h>
#include <execinfo.h>
void show_stackframe() {
void *trace[16];
char **messages = (char **)NULL;
int i, trace_size = 0;
trace_size = backtrace(trace, 16);
messages = backtrace_symbols(trace, trace_size);
printf("[bt] Execution path:\n");
for (i=0; i<trace_size; ++i)
printf("[bt] %s\n", messages[i]);
}
int func_low(int p1, int p2) {
p1 = p1 - p2;
show_stackframe();
return 2*p1;
}
int func_high(int p1, int p2) {
p1 = p1 + p2;
show_stackframe();
return 2*p1;
}
int test(int p1) {
int res;
if (p1<10)
res = 5+func_low(p1, 2*p1);
else
res = 5+func_high(p1, 2*p1);
return res;
}
int main() {
printf("First call: %d\n\n", test(27));
printf("Second call: %d\n", test(4));
}
