// This is similar to the GetStackFrames routine, except that it returns
// the stack trace only, and not the stack frame sizes as well.
// Example:
//      main() { foo(); }
//      foo() { bar(); }
//      bar() {
//        void* result[10];
//        int depth = GetStackFrames(result, 10, 1);
//      }
//
// This produces:
//      result[0]       foo
//      result[1]       main
//           ....       ...
//
// "result" must not be NULL.
