/*** mem.h - Definitions for Memory Manager
*
* Microsoft Confidential
* Copyright (C) Microsoft Corporation 1993-1994
* All Rights Reserved.
*
* The Memory Manager is a very thin layer on top of the native memory
* heap functions, allowing strong assertion checking and pointer
* validation in debug builds.
*
* Author:
* Benjamin W. Slivka
*
* History:
* 10-Aug-1993 bens Initial version
* 11-Aug-1993 bens Lift code from STOCK.EXE win app
* 12-Aug-1993 bens Improved comments
* 18-Mar-1994 bens strdup() now called _strdup(); renamed
* 18-May-1994 bens Allow turning off MemCheckHeap() in debug build
* (it can really, really slow things down!)
*
* Functions:
* MemAlloc - Allocate memory block
* MemFree - Free memory block
* MemStrDup - Duplicate string to new memory block
*
* Functions available in ASSERT build:
* MemAssert - Assert that pointer was allocated by MemAlloc
* MemCheckHeap - Check entire memory heap
* MemGetSize - Return allocated size of memory block
* MemSetCheckHeap - Control whether MemCheckHeap is done on every
* every MemAlloc and MemFree!
