*Purpose:
*       defines wprintf() - print formatted data
*
*Revision History:
*       05-16-92  KRS   Created from printf.c.
*       04-06-93  SKS   Replace _CRTAPI* with __cdecl
*       02-07-94  CFW   POSIXify.
*       09-06-94  CFW   Replace MTHREAD with _MT.
*       02-06-95  CFW   assert -> _ASSERTE.
*       03-07-95  GJF   Use _[un]lock_str2 instead of _[un]lock_str. Also,
*                       removed useless local and macros.
*       03-02-98  GJF   Exception-safe locking.

/***
*int wprintf(format, ...) - print formatted data
*
*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
*
*Exceptions:
