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]).

I finally found a reliable way to log the stack frames in x64, using the Windows function CaptureStackBackTrace(). As I did not want to update my SDK, I call it via GetProcAddress(LoadLibrary());

   typedef USHORT (WINAPI *CaptureStackBackTraceType)(__in ULONG, __in ULONG, __out PVOID*, __out_opt PULONG);
   CaptureStackBackTraceType func = (CaptureStackBackTraceType)(GetProcAddress(LoadLibrary("kernel32.dll"), "RtlCaptureStackBackTrace"));

   if(func == NULL)
       return; // WOE 29.SEP.2010

   // Quote from Microsoft Documentation:
   // ## Windows Server 2003 and Windows XP:  
   // ## The sum of the FramesToSkip and FramesToCapture parameters must be less than 63.
   const int kMaxCallers = 62; 

   void* callers[kMaxCallers];
   int count = (func)(0, kMaxCallers, callers, NULL);
   for(i = 0; i < count; i++)
      printf(TraceFile, "*** %d called from %016I64LX\n", i, callers[i]);
