+ *
+ * StackWalker.cpp
+ * https://github.com/JochenKalmbach/StackWalker
+ *
+ * Old location: http://stackwalker.codeplex.com/
+ *
+ *
+ * History:
+ * 2005-07-27 v1 - First public release on http://www.codeproject.com/
+ * http://www.codeproject.com/threads/StackWalker.asp
+ * 2005-07-28 v2 - Changed the params of the constructor and ShowCallstack
+ * (to simplify the usage)
+ * 2005-08-01 v3 - Changed to use 'CONTEXT_FULL' instead of CONTEXT_ALL
+ * (should also be enough)
+ * - Changed to compile correctly with the PSDK of VC7.0
+ * (GetFileVersionInfoSizeA and GetFileVersionInfoA is wrongly defined:
+ * it uses LPSTR instead of LPCSTR as first parameter)
+ * - Added declarations to support VC5/6 without using 'dbghelp.h'
+ * - Added a 'pUserData' member to the ShowCallstack function and the
+ * PReadProcessMemoryRoutine declaration (to pass some user-defined data,
+ * which can be used in the readMemoryFunction-callback)
+ * 2005-08-02 v4 - OnSymInit now also outputs the OS-Version by default
+ * - Added example for doing an exception-callstack-walking in main.cpp
+ * (thanks to owillebo: http://www.codeproject.com/script/profile/whos_who.asp?id=536268)
+ * 2005-08-05 v5 - Removed most Lint (http://www.gimpel.com/) errors... thanks to Okko Willeboordse!
