- *
- * StackWalker.cpp
- *
- *
- * 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 paremeter)
- * - 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!

- * Fixed Bug: SymDia is number 7, not 9!
- * 2008-09-11 v7 For some (undocumented) reason, dbhelp.h is needing a packing of 8!
- * Thanks to Teajay which reported the bug...
- * http://www.codeproject.com/KB/applications/leakfinder.aspx?msg=2718933#xx2718933xx
- * 2008-11-27 v8 Debugging Tools for Windows are now stored in a different directory
- * Thanks to Luiz Salamon which reported this "bug"...
- * http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=2822736#xx2822736xx
- * 2009-04-10 v9 License slihtly corrected (<ORGANIZATION> replaced)
- * 2010-04-15 v10 Added support for VS2010 RTM
