/*
**  Copyright (c) 1994, University of Kansas, All Rights Reserved
**
**  Include File:	LYLeaks.h
**  Purpose:		Header to convert requests for allocation to Lynx
**			custom functions to track memory leaks.
**  Remarks/Portability/Dependencies/Restrictions:
**	For the stdlib.h allocation functions to be overriden by the
**		Lynx memory tracking functions all modules allocating,
**		freeing, or resizing memory must have LY_FIND_LEAKS
**		defined before including this file.
**	This header file should be included in every source file which
**		does any memory manipulation through use of the
**		stdlib.h memory functions.
**	For proper reporting of memory leaks, the function LYLeaks
**		should be registered for execution by atexit as the
**		very first executable statement in main.
**	This code is slow and should not be used except in debugging
**		circumstances (don't define LY_FIND_LEAKS).
**	If you are using LY_FIND_LEAKS and don't want the LYLeak*
**		memory functions to be used in a certain file,
**		define NO_MEMORY_TRACKING before including this file.
**	The only safe way to call the LYLeak* functions is to use
**		the below macros because they depend on the static
**		string created by __FILE__ to not be dynamic in
**		nature (don't free it and assume will exist at all
**		times during execution).
**	If you are using LY_FIND_LEAKS and LY_FIND_LEAKS_EXTENDED and
**		want only normal memory tracking (not extended for
**		HTSprintf/HTSprintf0) to be used in a certain file,
**		define NO_EXTENDED_MEMORY_TRACKING and don't define
**		NO_MEMORY_TRACKING before including this file.
**  Revision History:
**	05-26-94	created for Lynx 2-3-1, Garrett Arch Blythe
**	10-30-97	modified to handle StrAllocCopy() and
**			StrAllocCat(). - KW & FM
**	1999-10-17	modified to handle HTSprintf0 and HTSprintf(),
**			and to provide mark_malloced, if
**			LY_FIND_LEAKS_EXTENDED is defined. - kw
