*Purpose:
* Prints formatted data on stdout using the format string to
* format data and getting as many arguments as called for
* Uses temporary buffering to improve efficiency.
* _output does the real work here
*
*Entry:
* wchar_t *format - format string to control data format/number of arguments
* followed by list of arguments, number and type controlled by
* format string
*
*Exit:
* returns number of wide characters printed
