Question

I’ve opened winnt.h header file and found there this two lines:

typedef wchar_t WCHAR;

and

typedef WCHAR TCHAR, *PTCHAR;

but there was comment in one of my posts that there is some difference between them. Then what is the difference?

Answer 1

If you read the entire header, you will find:

#ifdef _UNICODE
typedef WCHAR TCHAR;
#else
typedef char TCHAR;
#endif

or words to that effect.

Perhaps MS has removed the narrow option of late.
