secury swprintf without crt

Hi ,
i have advice on the folloing code:
wchar_t* day = new wchar_t [11];
swprintf(day,L"%4d-%2d-%2d",yy,mm,dd);

how to make sure that my 'day' didn't get string bigger then 20 chars?

found:
swnprintf_s(day,size,L"%4d-%2d-%2d",yy,mm,dd);
but it requires crt

any suggestions?

Yes. Don't use swprintf. Use a wostringstream instead.
