+ * 

+ * 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!

+ *  2008-08-04   v6    - Fixed Bug: Missing LEAK-end-tag

+ *                       http://www.codeproject.com/KB/applications/leakfinder.aspx?msg=2502890#xx2502890xx

+ *                       http://www.codeproject.com/KB/applications/leakfinder.aspx?msg=1824718#xx1824718xx

+ *                       Fixed Bug: Compiling with "/Wall"

+ *                       http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=2638243#xx2638243xx

+ *                       Fixed Bug: Now checking SymUseSymSrv

+ *                       http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=1388979#xx1388979xx

+ *                       Fixed Bug: Support for recursive function calls

+ *                       http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=1434538#xx1434538xx

+ *                       Fixed Bug: Missing FreeLibrary call in "GetModuleListTH32"

+ *                       http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=1326923#xx1326923xx

+ *                       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
