2*stdlib.h - declarations/definitions for commonly used library functions
3*
4*   Copyright (c) 1985-1988, Microsoft Corporation.  All rights reserved.
5*
6*Purpose:
7*   This include file contains the function declarations for
8*   commonly used library functions which either don't fit somewhere
9*   else, or, like toupper/tolower, can't be declared in the normal
10*   place (ctype.h in the case of toupper/tolower) for other reasons.
