/***
*output.c - printf style output to a FILE
*
* Copyright (c) 1989-1997, Microsoft Corporation. All rights reserved.
*
*Purpose:
* This file contains the code that does all the work for the
* printf family of functions. It should not be called directly, only
* by the *printf functions. We don't make any assumtions about the
* sizes of ints, longs, shorts, or long doubles, but if types do overlap,
* we also try to be efficient. We do assume that pointers are the same
* size as either ints or longs.
* If CPRFLAG is defined, defines _cprintf instead.
* **** DOESN'T CURRENTLY DO MTHREAD LOCKING ****
