Data Type Mappings
The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.
The latest version of this topic can be found at Data Type Mappings.
These data-type mappings are defined in TCHAR.H and depend on whether the constant _UNICODE or _MBCS has been defined in your program.
For related information, see Using TCHAR.H Data Types with _MBCS Code.
