Enough geekery! That should of course be

wprintf(L”%S”, …)

and not

wprintf(”%S”, …)

Enough geekery!

In Microsoft's runtime library at least, wprintf("%S", ...) behaves symmetrically and will print a single-byte-character string into the resulting wide string output. If you've ever had the misfortune to work with TCHAR strings, then you may see a dilema here: _tprintf(_T("%s"), ptr) allows you put a TCHAR* into the resulting TCHAR output. So what is the type of ptr in the expression _tprintf(_T("%S"), ptr) ? !TCHAR ? I believe also that the format string “%S” is synonymous with “%ls”.
