*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:
*       char *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 characters printed
