        You seem to not read my code very well:

#define tchar_size(x) (sizeof(x) / sizeof(TCHAR))

        Let's assume this:

        TCHAR buf[512];

        In UNICODE builds, tchar_size(buf) expands to: (sizeof(buf) /
sizeof(TCHAR)) which is (1024 / 2) or 512.

        In non-UNICODE builds, tchar_size(buf) expands to (sizeof(buf) /
sizeof(CHAR)) which is (512 / 1) or 512.

        Any questions?
