How to Log Stack Frames with Windows x64

Question

I am using Stackdumps with Win32, to write all return adresses into my logfile. I match these with a mapfile later on (see my article [Post Mortem Debugging][1]).

When using StackWalk64 you are iterating through the thread's entire stack whether there is valid data or not. Once you hit a return address of 0 you should terminate the walk, like so:

for (ULONG Frame = 0; ; Frame++)
{
  if (FALSE == StackWalk64(...))
  {
    printf("Stack walk failed!\n");
    break;
  }  

  if (stackFrame.AddrPC.Offset == 0)
  {
    printf("Stack walk complete!\n");
    break;
  }

  do_something();
}
