Integer to string function doesn't account for 0

I've been using this function to convert integers into wide character strings, but I realized the function fails if the integer to be converted is 0.  This happens because the for loop breaks if it finds that val = 0.  

What are some workarounds to this problem?  

wchar_t* itowcs(int val, int base)
{
      static wchar_t buf[32] = {0};
      int i = 30;
      for(; val && i ; --i, val /= base) {
            buf[i] = L"0123456789abcdef"[val % base];
      }
      return &buf[i+1];
}

Why not using this function instead of re-inventing the wheel
wchar_t * _itow( int value, wchar_t *string, int radix );
Or,
wchar_t * itow( int value, wchar_t *string, int radix );
