2No way of doing this using standard C++ - your specific compiler may have something you can use.anon– anon2010-07-31 14:14:39 +00:00Commented Jul 31, 2010 at 14:14

If you're using g++ (gcc) and don't mind the code being non-portable, you could try following the wise words of "tombarta":
(shameless copy from tombarta):
#include <execinfo.h>
void print_trace(FILE *out, const char *file, int line)
{
const size_t max_depth = 100;
size_t stack_depth;
void *stack_addrs[max_depth];
char **stack_strings;
stack_depth = backtrace(stack_addrs, max_depth);
stack_strings = backtrace_symbols(stack_addrs, stack_depth);
fprintf(out, "Call stack from %s:%d:\n", file, line);
for (size_t i = 1; i < stack_depth; i++) {
fprintf(out, " %s\n", stack_strings[i]);
}
free(stack_strings); // malloc()ed by backtrace_symbols
fflush(out);
}
I haven't tried this myself, so I do not know if it works.
