SDL_WPRINTF_VARARG_FUNCV - Macro that annotates a va_list function that operates like wprintf.

       This macro is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.20                        SDL_WPRINTF_VARARG_FUNCV(3)

       If we were to annotate vfwprintf:

              int vfwprintf(FILE *f, const wchar_t *fmt, va_list ap) SDL_WPRINTF_VARARG_FUNC(2);

       This notes that the second parameter should be a wprintf-style format wide string, followed by a va_list.
       The compiler or other analysis tools can warn when this doesn't appear to be the case.

       On compilers without this annotation mechanism, this is defined to nothing.

       This  can  (and  should)  be used with SDL_PRINTF_FORMAT_STRING as well, which between them will cover at
       least Visual Studio, GCC, and Clang.
