// 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.
