Updated Platform Support
Where necessary, the DbgHelp library has been widened to support both 32- and 64-bit Windows. The original function and structure definitions are still in DbgHelp.h, but there are also updated versions of these definitions that are compatible with 64-bit Windows. If you use the updated functions in your code, it can be compiled for both 32- and 64-bit Windows. Your code will also be more efficient, since the original functions simply call the updated functions to perform the work.
For example, DbgHelp.h contains definitions for SymUnloadModule (original function) and SymUnloadModule64 (updated function). These definitions are nearly identical, but use different types for the BaseOfDll parameter. (SymUnloadModule uses the DWORD type, while SymUnloadModule64 uses the DWORD64 type.) If you write your code to use SymUnloadModule64, it can be compiled for both 32- and 64-bit Windows. The code is also more efficient than if it were to call SymUnloadModule.
