What does the Unicode format code mean?

NTFSD
1

The “Format” parameter of KdPrint supports the printf-style formatting codes. However, what does the Unicode format code (%C, %S, %lc, %ls, %wc, %ws, %wZ) mean? I can’t find the detail information in MSDN. Can anybody tell me where can I find the detail information?

This means that the corresponding parameter must be a pointer to Unicode
chars, or UNICODE_STRING.

That’s great, but where are all these formats documented?
That is, if they in fact are documented.

Besides, this info, useful as it is, is not exact.

It says that “AFAIK, printf() and wprintf() functions in crtdll
don’t support the ‘%Z’ and ‘%wZ’ formats.”, but here we are:

// wZ.cpp
// compile and link under VS2003 as a
// user mode console project

#include <windows.h> // should preceed Ntsecapi.h
#include <ntsecapi.h> // for UNICODE_STRING
#include <stdio.h> // for printf

int main() {
UNICODE_STRING uString;
uString.Length = 18;
uString.MaximumLength = 20;
uString.Buffer = L"some text";
printf(“%wZ”, &uString);
return 0; // for a breakpoint
}
// on-screen result:
//“some text”
// with cursor right after the last “t”
